Vinyl Ester Resin: Zimene Zaka 35 M'ngalande Zinandiphunzitsa Zokhudza Kupeza Ndalama Moyenera

Ndakhala ndikugwiritsa ntchito zinthu zopangidwa ndi composites kuyambira mu 1989. Kwa zaka makumi atatu ndi zisanu ndikugwira ntchito yopumira styrene, kuwotcha zala zanga pa laminate yotulutsa mafuta, komanso kuchita zinthu ndi ogulitsa omwe amalonjeza dziko lonse lapansi ndikutumiza zinyalala. Ngati mukuwerenga izi, mwina mukufunikautomoni wa ester wa vinylpa chinthu chofunika. Thanki ya mankhwala. Bwato lozungulira. Njira yotsukira. Ndikukuuzani zomwe ndaphunzira zokhudza kupezawogulitsa utomoni wa vinyl ester amene sadzawononga ntchito yanu. Ndili ndi maganizo. Sindidzawafewetsa.

Siyani Kusokoneza Vinyl Ester ndi Polyester

Utomoni wa ester wa vinylndi msuwani wa epoxy. Mumatenga msana wa epoxy ndikuwugwiritsa ntchito ndi methacrylic acid. Magulu a ester amathera kumapeto kwa unyolo wokha. Ndiwo luso lonse la molekyulu. Magulu ochepa a ester amatanthauza malo ochepa owukira asidi ndi alkali.

Polyester ili ndi magulu a ester pa unyolo wonse. Ichi ndichifukwa chake matanki a polyester amasweka patatha zaka zisanu akugwira ntchito ya mankhwala. Matanki a vinyl ester akhalapo kwa zaka makumi awiri. Ndawagwiritsa ntchito onse awiri. Kusiyana kwake sikobisika.

Ndaona ogula akuvala polyester ya isophthalic chifukwa "ili pafupi mokwanira." Siili pafupi mokwanira. Isophthalic ndi utomoni wabwino. Siili pafupi mokwanirautomoni wa ester wa vinylNgati kasitomala wanu wasankha vinyl ester ndipo mwatumiza iso polyester, mudzagwidwa. Kuyesa kwa labu kumatenga mphindi khumi ndi zisanu. Kenako dzina lanu lili pa lipoti la kulephera. Musachite zimenezo.

Epoxy imagwira ntchito bwino kuposa vinyl ester papepala. M'malo mwake, epoxy imadula kawiri, imafunika ma uvuni okonzedwanso, ndipo ma laminator anu sadzakonda kugwiritsa ntchito.Utomoni wa ester wa vinylnjira zofanana ndi polyester. Mutha kuziyika pamanja, kuzipopera, kuzipukuta, kuziyendetsa mu RTM. Kusinthasintha kumeneku ndi chifukwa chakeutomoni wa ester wa vinylimalamulira msika wa dzimbiri wapakati. Epoxy ili ndi ndege. Polyester ili ndi zinthu zotsika mtengo. Vinyl ester ili ndi chilichonse chomwe chili pakati.

Kukambirana kwa Mtengo Palibe Amene Akufuna Kukhala Naye Moona Mtima

Nayi zomwewopanga utomoni wa vinyl estermtengo wake ndi wofanana. Standard bisphenol-A vinyl ester imagwira ntchito kuyambira 2,800 mpaka 3,500 pa tani. Novolac epoxy vinyl ester — yomwe imatentha kwambiri — imakhala pa 3,800 mpaka 4,500. Epoxy imayamba pa 4,500 ndipo imapitirira 7,000. Ortho polyester ndi yosakwana $1,800.

Utomoni wa ester wa vinylmtengo wake ndi wowirikiza kawiri kuposa mtengo wa iso polyester.

Koma mu 30% ya sulfuric acid, vinyl ester imakhala nthawi yayitali katatu kapena kasanu.

Chaka chatha ndinatulutsa ma cores kuchokera mu thanki ya mankhwala. Zaka khumi ndi zisanu ndikugwira ntchito. Liner ya vinyl ester inali isanathe. Tanki yomweyo, liner ya polyester backup, momwe ntchitoyo imakhalira. Ndikanatha kuswa utomoni wa polyester ndi chala changa chachikulu ndi chala changa chakutsogolo.

Kotero pamene woyang'anira kugula zinthu anandiuza kuti vinyl ester ndi yokwera mtengo kwambiri, ndimafunsa funso limodzi. Kodi thankiyo imawononga ndalama zingati ikalephera? Kuyeretsa chilengedwe kokha kumawononga ndalama zokwana khumi kuposa mtengo wa resin. Mlandu ndi wokwera kwambiri. Masamu ndi osavuta. Anthu safuna kuchita izi chifukwa nambala yoyambirira imawoneka yayikulu pa PO.

Zabwinowogulitsa utomoni wa vinyl esterZimakuthandizani kupanga chikwama cha moyo wonse. Choyipa chimangotchula mtengo wa pa kilogalamu imodzi ndipo chimasowa.

Wogulitsa Kapena Wopanga — Phunzirani Kusiyanitsa

Theka la makampani omwe ali pa nsanja za B2B amadzitcha okha "wogulitsa utomoni wa vinyl ester"Ndi amalonda. Alibe reaktarakitala. Alibe labu. Amagula ku fakitale yomwe imagula epoxy ku fakitale ina. Utomoni umaonekera padoko lanu ndi manambala a batch omwe sagwirizana ndi CoA. Kukhuthala kwachepa ndi 40%. Mukuyimba foni kuti mudandaule. Palibe amene ayankha.

Umu ndi momwe mungawachotsere mwachangu.

Funsani zithunzi za reactor zomwe zili ndi tsiku lomwe lilipo papepala lomwe lili pachithunzicho. Funsani zomwe zatuluka mwezi uliwonse mu matani a metric. Funsani ma CoA kuchokera m'magulu atatu otsatizana. Yeniyeniwopanga utomoni wa vinyl esteramayankha mafunso awa nthawi yomweyo. Wogulitsa akuti “ndiye ndiyang'ane ndikukuyankhani.” Chiganizo chimenecho chimakuuzani zonse.

Ndinapita kwa “wopanga” mu 2019 yemwe anali ndi tsamba lokongola lowonetsa holo ya reactor yopanda banga. Ndinafika pamasom'pamaso. Malowa anali nyumba yosungiramo zinthu yokhala ndi ng'oma zolembedwanso. Palibe reactor. Palibe labu. Munthu m'modzi wokhala ndi foni. Ndinatuluka. Mnzanga sanataye. Anataya $80,000 chifukwa cha ndalama zochepa zomwe zinagwera mu ng'oma panthawi yotumiza. “Wopereka” anatseka nambala yake.

Katundu Wofunika Pamwamba pa Sitolo, Osati Pa Kabukuka

Sindikusamala za pepala la deta. Ndikusamala zomwe zimachitika utomoni ukagundana ndi nkhungu.

Kukhuthala. Ngati ili pamwamba pa 500 mPa·s pa 25°C, ma laminator anu adzalimbana ndi kunyowa pa nsalu yolukidwa. Adzaichepetsa ndi styrene. Tsopano mwachepetsa utomoni. Katundu wake watsika. Woperekayo akukudzudzulani chifukwa chowonjezera styrene. Mukumudzudzulani wogulitsa chifukwa chotumiza utomoni wokhuthala. Ndawona mkangano uwu ukuchitika kambirimbiri. Kuthetsa vutoli n'kosavuta. Gulani kuchokera kuwopanga utomoni wa vinyl esteramene amalamulira kukhuthala kwa mphamvu pakati pa 200 ndi 400 mPa·s. Mosalekeza.

Nthawi ya jeli. Ndinagwira ntchito ndi gulu lomwe linasungunuka mu mphindi 12 pa kutentha kwa sitolo kwa 35°C. Mphindi 12. Simungathe kuyika chogwirira cha manway mu mphindi 12. Mukufunika mphindi 25 mpaka 40 kuti mugwire ntchito yolimba yokonza ndi manja.wogulitsa utomoni wa vinyl esterMuyenera kusintha phukusi la promoter kuti ligwirizane ndi shopu yanu. Cobalt naphthenate yambiri m'masitolo ozizira. Ochepa kwa otentha. BPO ngati mukuyeretsa pansi pa 15°C. Ngati wogulitsa sangathe kusintha njira yoyeretsera, akukugulitsani njira yokhazikika ndipo akuyembekeza kuti mugwiritse ntchito. Zimenezo ndi zobwerera m'mbuyo. Utomoni umagwirira ntchito kwa inu. Simugwira ntchito pa utomoni.

Kulimba kwa Barcol. Iyenera kufika madigiri 35 mpaka 40 mkati mwa maola 24 kutentha kwa chipinda. Kuima pa madigiri 28 patatha masiku awiri kumatanthauza kuti pali vuto. Kaya MEKP peresenti yatsika, kapena utomoni ndi wakale, kapena promoter yawonongeka chifukwa chosungira molakwika. Ndawona utomoni "watsopano" womwe kwenikweni unali ndi miyezi khumi ndi isanu ndi itatu chifukwa unali m'nyumba yosungiramo zinthu zotentha ya wogawa. Promoter anali atayamba kale kuchitapo kanthu mkati mwa ng'oma. Mumapeza machiritso ofooka komanso malo omata omwe samakhala olimba mokwanira.

Kumene Ndaona Vinyl Ester Win — ndi Kumene Anthu Amawononga Ndalama

Ndatchulautomoni wa ester wa vinylya matanki osungiramo mankhwala, ma ducts otsukira, ma scrubber, mapaipi obisika, ndi ma profiles omangidwa. Imagwira ntchito bwino kwambiri pokonza zinthu zowononga komanso kulikonse komwe mukufuna kapangidwe kake ka zaka 20.

Zomera za mankhwala. Ndicho chachikulu.Utomoni wa ester wa vinylndiye chinthu chokhazikika chomwe chimagwiritsidwa ntchito posungira madzi. Ngati mukumanga thanki yokhala ndi 30% ya hydrochloric acid, palibe njira ina yotsika mtengo yomwe ingapulumuke. Ndikunena zimenezo momveka bwino.

Madzi a m'nyanja. Madzi amchere amadya polyester. Vinyl ester imakhalapo kwa zaka zambiri. Opanga maboti anzeru amagwiritsa ntchito vinyl ester pakhungu lakunja pansi pa madzi ndipo amasintha kukhala polyester kuti apange mkati. Mumapeza chotchinga cha dzimbiri pomwe mukuchifuna. Mumasunga ndalama pomwe simukuzifuna.

Koma apa ndi pomwe ndimakwiya. Ndaona mainjiniya akusankha vinyl ester ngati thanki yamadzi pa kutentha kozungulira. Madzi. Kutentha kwa chipinda. Polyester ya Iso imagwira ntchito imeneyi kwa zaka makumi awiri pa theka la mtengo. Ndimauza makasitomala izi ngakhale zitakhala kuti ndimagulitsa utomoni wochepa. Ngati mutchula mopitirira muyeso, mukuwononga ndalama za kasitomala wanu. Pamapeto pake amapeza zimenezo ndikupeza wina amene angawauze zoona.

Kusunga Zinthu Kudzapha Phindu Lanu

Utomoni wa ester wa vinylIli ndi nthawi yosungiramo zinthu kuyambira miyezi itatu mpaka isanu ndi umodzi pa kutentha kwa 25°C. 10°C iliyonse pamwamba pake imachepetsa nthawi yosungiramo zinthu pakati.

Ndaona ogula akuyitanitsa chidebe chodzaza, ndikuchiyika m'nyumba yosungiramo zinthu zopangidwa ndi chitsulo mu Julayi, ndipo ndikudabwa chifukwa chake utomoni unalowa mu ng'oma patatha milungu isanu ndi itatu. Kutentha kumapha vinyl ester. Chothandizira chimayamba kuchitapo kanthu. Kukhuthala kumakwera. M'mawa wina mutsegula ng'oma ndipo imakhala yolimba.

Ngatiwogulitsa utomoni wa vinyl esterMagalimoto ochokera kumayiko ena, mumataya nthawi yosungiramo katundu kwa milungu itatu kapena inayi. Kasitomu amadya sabata ina. Nyumba yanu yosungiramo katundu imakhalapo kwa mwezi umodzi. Mutha kukhala ndi milungu isanu ndi umodzi yogwiritsidwa ntchito mukatsegula ng'oma yoyamba.

Itanitsani zinthu zochepa pafupipafupi. Mtengo pa kilogalamu umakwera pang'ono. Mumataya utomoni wochepa kwambiri. Ndinasintha kasitomala wanga kuchoka pa kutumiza katundu wa sitima yapamadzi kupita ku IBC totes pamwezi. Zinyalala zake zinatsika kuchoka pa 12% kufika pansi pa 2%. Masamuwo anagwira ntchito.

Zikalata Sizosankha

ISO 9001 ndiye muyezo. Ngatiwopanga utomoni wa vinyl estersakuigwira, siyani kukambirana.

Kutumiza ku Europe? Mukufuna kulembetsa ku REACH. Palibe REACH, palibe chilolezo cha msonkho. Ndinaonera chidebe chonse cha kasitomala chikusungidwa ku Rotterdam kwa milungu itatu. Utomoni unalibe zikalata za REACH. Ndalama zolipirira utomoni zinapitirira mtengo wa utomoni. Wogulitsayo anagwedeza mapewa ake.

Mapulogalamu apamadzi amafunika kuvomerezedwa ndi mtundu wa DNV kapena ABS. Magiredi oletsa moto amafunika UL 94 V-0. Onetsetsani kuti satifiketi ikukhudza mtundu womwe mukugula. Ndapeza ogulitsa akuwonetsa satifiketi ya UL ya mtundu wina wazinthu ndipo ndikuyembekeza kuti sindingazindikire. Ndazindikira.

Zimene Ndimauza Kasitomala Watsopano Aliyense

Pezaniwopanga utomoni wa vinyl esteramene amayesa gulu lililonse ndipo amatumiza CoA musanafunse. Katswiri wa zamankhwala pa ntchito ayenera kuyankha foni pamene utomoni wanu sungathe kuchira. Kupaka kuyenera kukhala kwa milungu itatu m'chidebe. Zikalata ziyenera kufika musanazitsatire.

Yankhani kaye. Nthawi zonse. Matani imodzi mpaka asanu. Yesani mzere wanu weniweni wopangira. Osati labu. Labu ndi yabodza. Malo ogulitsira amanena zoona. Lembani nthawi ya gel malinga ndi kutentha kwa sitolo yanu. Yang'anani nthawi yamadzi pa reinforcement yanu. Yesani nthawi ya demold. Yang'anani malo osungira ndi maso a nsomba pamwamba pa gelcoat.

Kenako yerekezerani ndi chilichonse chomwe mukugwiritsa ntchito tsopano. Ngati utomoni watsopanowo ukuchira msanga, ukunyowa bwino, ndipo pamwamba pake pali poyera, mwapeza wogulitsa wanu. Ngati chilichonse mwa zinthuzo chili choipa kwambiri, pitirizani kufufuza.

Ndagwira ntchito ndiogulitsa ma resin a vinyl esterkuchokera ku China, India, Europe, ndi US. Zabwino zimapezeka kulikonse. Geography siimasankha mtundu. Kuwongolera njira kumasankha mtundu. Fakitale yoyendetsedwa bwino ku Shandong yapambana ntchito yosakhazikika ku Stuttgart. Ndawona zonse ziwiri.

Utomoni wotsika mtengo kwambiri si utomoni wotsika mtengo kwambiri. Ndinaphunzira zimenezo mu 1997. Ndinalipira ndi thanki yolephera komanso kasitomala wokwiya kwambiri. Phunziro silinasinthe kwa zaka 28. Musaphunzire momwe ndinachitira.
