1. Chitoliro chophatikiza cha PVC/FRP ndi chitoliro chophatikiza cha PP/FRP

PVC/FRPchitoliro chophatikizanaIli ndi chitoliro cholimba cha PVC, ndipo mawonekedwe ake amachiritsidwa ndi mankhwala apadera komanso achilengedwe ndipo amakutidwa ndi guluu wa R wosinthika wokhala ndi zinthu za PVC ndi FRP. Chitolirochi chimaphatikiza kukana dzimbiri kwa PVC ndi mphamvu yayikulu komanso kukana kutentha kwabwino kwa FRP ndikukulitsa kuchuluka kwa ntchito ya chinthu chimodzi.Chitoliro cha PVC ndi chitoliro cha FRPMu mafakitale amafuta, makampani opanga mankhwala, makina, zitsulo, makampani opanga magetsi, magetsi, migodi, ndi mafakitale ena ambiri, imatha kuonedwa ngati payipi yothetsera kunyamula zinthu zowononga ndipo imatha kusintha chitoliro chachitsulo chosapanga dzimbiri. Chitoliro chophatikizika cha PP/FRP chili ndi chitoliro cha PP, mawonekedwe ake amakonzedwa ndi mankhwala, ulusi wamphamvu kwambiri ndi utomoni wopangidwa zimagwiritsidwa ntchito ngati zigawo, ndipo zimaphatikizidwa ndi makina opindika. Chitolirocho chili ndi mawonekedwe a kukana dzimbiri kwa PP ndi mphamvu yapamwamba ya FRP komanso kukana kutentha kwabwino, motero kukulitsa kuchuluka kwa chitoliro chimodzi cha PP, chomwe chimagwiritsidwa ntchito makamaka muzakudya, zamankhwala, ndi mafakitale ena.

2. Njira ya FRP

Mapaipi oyendetsera ntchito a FRP amagwiritsidwa ntchito kwambiri posamalira madzi, zimbudzi, mafuta, makampani opanga mankhwala, magetsi, zitsulo, mankhwala, ndi zina. Ali ndi ubwino wokhala opepuka, amphamvu kwambiri, okana dzimbiri, komanso osavuta kukhazikitsa, komanso kukonza. Chogulitsachi chagwiritsidwa ntchito bwino mdziko lonselo.

3. Chitoliro choteteza chingwe cha FRP

Chitoliro choteteza chingwe cha FRP ndi mtundu wa chitoliro chopangidwa ndi njira yozungulira yoyendetsedwa ndi kompyuta kapena njira yopukutira yokhala ndi utomoni ngati matrix komanso yopitiliraulusi wagalasi ndipo nsalu yake ndi yolimba. Ili ndi mawonekedwe a mphamvu zambiri, kulimba bwino, kutchinjiriza magetsi, kuletsa moto, kukana kutentha bwino, kukana dzimbiri, kukhala ndi moyo wautali, ndi zina zotero. Chubu choteteza chingwe cha FRP ndi choyenera kugwiritsa ntchito zingwe zobisika pansi ngati machubu oteteza ndipo chimagwiritsidwanso ntchito nthawi zambiri monga zingwe zowoloka milatho ndi mitsinje. Kugwiritsa ntchito chofananiracho

Kuphatikiza kwa pilo ya chitoliro chaukadaulo, kumatha kupanga chitoliro chokhala ndi zigawo zambiri komanso chokhala ndi mizati yambiri.

4. Chitoliro cha pulasitiki cholimbikitsidwa ndi ulusi wagalasi

Mapaipi opondereza a FRP ali ndi mphamvu zabwino zamakanika ndi zakuthupi, ndi opepuka, ali ndi mphamvu zambiri, ndipo ndi osavuta kuyika. Kuphatikiza apo, ali ndi mphamvu zabwino zotsutsana ndi dzimbiri komanso moyo wautali, womwe ndi nthawi 4-5 kuposa chitoliro chachitsulo; kukana kutentha kwambiri, kutentha kwabwinobwino kogwira ntchito kumatha kufika 100 ° C; Khoma lamkati ndi losalala kwambiri, kusinthasintha kwa sing'anga ndi kwabwino, palibe kukula, palibe sera, ndipo ndalama zogwirira ntchito ndi kukonza mapaipi zimachepetsedwa. Kuteteza bwino, palibe kuipitsa kwina.

5. FRP flue

Zofunikira pa kuteteza chilengedwe m'dziko langa zikuchulukirachulukira, ukadaulo wochotsa mpweya wonyowa m'mafakitale amagetsi wakhala ukugwiritsidwa ntchito kwambiri, ndipo mayunitsi ambiri atsopano agwiritsa ntchito ukadaulo wochotsa mpweya wonyowa m'mafakitale amagetsi. Kugwiritsa ntchito kwambiri njira yochotsera mpweya wonyowa m'mafakitale amagetsi, komanso mphamvu zake zapamwamba zochotsera mpweya wonyowa m'mafakitale amagetsi kumachepetsa kwambiri kuchuluka kwa sulfure dioxide mu mpweya wonyowa womwe umatulutsidwa ndi fakitale yamagetsi, zomwe zimapangitsa kuti zikhale zotheka kugwiritsa ntchito ukadaulo wophatikiza nsanja ya utsi.

6. payipi ya mchenga ya pulasitiki yolimbikitsidwa ndi ulusi wagalasi

Mapaipi odzaza mchenga wa FRP ali ndi mphamvu yolimbana ndi dzimbiri komanso amakhala ndi moyo wautali ndipo amatha kupirira kuwonongeka kwa nthawi yayitali ndi ma acid osiyanasiyana, alkalis, mchere, zosungunulira zachilengedwe, madzi a m'nyanja, zimbudzi, ndi mankhwala ena. Mapaipi okhala ndi makhalidwe osiyanasiyana amatha kusankhidwa malinga ndi mitundu yosiyanasiyana ya ma media ndi kutentha kogwirira ntchito; ali ndi makhalidwe abwino kwambiri a makina. Chifukwa chakuti matope a resin amawonjezeredwa pakati pa khoma la chitoliro, kulimba kwa chitolirocho kumawonjezeka kwambiri, ndipo ndi koyenera kuyikidwa m'malo osiyanasiyana a nthaka ndi pansi pa nyanja; magwiridwe antchito a hydraulic ndi abwino kwambiri. Pamwamba pa payipi ya FRP ndi yosalala kwambiri ndipo kukana kukangana ndi kochepa (n≤0.0084), zomwe zingathandize kuchepetsa kwambiri kutayika kwa kuthamanga panjira ndikuwonjezera kuchuluka kwa madzi. Pansi pa kuchuluka komweko kwa madzi, mapaipi ang'onoang'ono kapena pampu yoperekera mphamvu yaying'ono ingagwiritsidwe ntchito. Potero kuchepetsa ndalama zoyambira za polojekitiyi, kusunga mphamvu (kuchepetsa ndalama zogwirira ntchito); luso labwino lopanga, kusinthasintha kwakukulu, komwe kungasinthidwe kuti kugwirizane ndi kupanikizika kosiyanasiyana kwa ntchito, pakati, kuuma (kapena kubisika) mwa kusintha zofunikira pakusankha zinthu, ngodya yozungulira ndi kuya kwa kapangidwe ka zigawo), kuti apange mapaipi a FRP okhala ndi milingo yosiyanasiyana ya kupanikizika ndi zinthu zapadera; oletsa kuipitsa, osapha poizoni. Khoma losalala lamkati silikula, silibala tizilombo toyambitsa matenda monga algae, ndipo silikhala ndi kuipitsidwa kwina kwa madzi. Mapaipi opangidwa ndi utomoni wapamwamba wa chakudya angagwiritsidwe ntchito kunyamula zakumwa.

Ife timapanga ndife akatswirifiberglass direct roving Opanga, zinthu zathu sizimangophatikizapo 1200tex-2400tex yokha, komanso kuyenda molunjika kosazolowereka monga 300-700tex, komanso timapereka ntchito zomwe zasinthidwa.
