Chitoliro cha pulasitiki cha PVC chimalimbana ndi kutentha kwambiri pomanga

Mapaipi apulasitiki a PVC-Undi ma resini a thermoplastic a amorphous opangidwa ndi vinyl chloride monomer pogwiritsa ntchito polymerisation reaction kuphatikiza zowonjezera zina (monga zokhazikika, mafuta odzola, zodzaza, ndi zina zotero). Mapaipi apulasitiki a pvc-U amasinthidwa posakaniza ndi ma resini ena kuwonjezera pa zowonjezera, zomwe zimapangitsa kuti zikhale zothandiza kwambiri. Ma resini awa ndi CPVC, PE, ABS, EVA, MBS, ndi zina zotero. UPVC ili ndi kukhuthala kwakukulu kosungunuka komanso kusungunuka kosauka, ndipo ngakhale kuthamanga kwa jakisoni ndi kutentha kosungunuka kwawonjezeka, kusintha kwa kusungunuka sikofunikira kwenikweni. Kuphatikiza apo, kutentha kwa utomoni kumakhala pafupi kwambiri ndi kutentha kwa kutentha, ndipo kutentha komwe kungapangidwe ndi kochepa kwambiri, komwe ndi chinthu chovuta kuchipanga.
makhalidwe;
Chitoliro cha pulasitiki cha PVC-U chili ndi mphamvu zabwino zopindika, kukana mankhwala, mphamvu ya makina, kukana ukalamba komanso kukana kutentha.
Mphamvu yonyamula katundu:
Mapaipi apulasitiki a PVC-U amatha kupirira kupsinjika kwakukulu kwa phazi popanda kusweka.
Malo ogwiritsira ntchito mapaipi apulasitiki a PVC-U:
Kukongoletsa mawaya amagetsi, kukongoletsa mawaya, koyenera kunyamula zakumwa ndi mafuta, kuteteza chingwe chamagetsi, kuteteza mawaya a magalimoto, makina ogwiritsira ntchito zida zamakina, zida zodzichitira zokha, ndi zina zotero.
Chitoliro cha pulasitiki cha PVC-UChitoliro cha pulasitiki cha PVC-U ndi chopepuka, mphamvu yokoka ndi 1/5 yokha ya chitoliro chachitsulo, chosavuta kugwira, kunyamula ndi kunyamula, kumanga, kungapulumutse ndalama zomangira. Chitoliro cha pulasitiki cha PVC-U chili ndi kukana dzimbiri bwino, kukana mankhwala bwino Chitoliro cha pulasitiki cha PVC-U chili ndi kukana asidi bwino, kukana alkali, kukana dzimbiri, kwa makampani opanga mankhwala, madzi otayira, zimbudzi zaukhondo ndi ntchito zina ndizoyenera kwambiri. Chitoliro cha pulasitiki cha PVC-U chili ndi makoma osalala komanso kukana madzi pang'ono, kukana kwake kolimba ndi 0.009 yokha, komwe ndi kotsika kuposa mapaipi ena, ndipo mu calibre yomweyo, kuthamanga kwa madzi kumakhala kwakukulu ndipo palibe sikelo yolumikizidwa. Chitoliro cha pulasitiki cha PVC-U chili ndi mphamvu yabwino yamakina Chitoliro cha PVC chili ndi kukana bwino kuthamanga kwa madzi ndi mphamvu ya kukhudza, kutentha kwa chipinda, chitoliro cha pulasitiki cha PVC-U chili choyenera ntchito zomangira mapaipi pansi pa mikhalidwe yosiyanasiyana.
Chitoliro chabwino cha PVC-U choteteza magetsi chili ndi chitoliro chamagetsi chapamwamba kwambiri, choyenera waya, chingwe cha waya, chingagwiritsidwe ntchito kwambiri pakulankhulana, mapaipi amphamvu komanso mapaipi a waya omangira nyumba. Chitoliro cha PVC sichikhudza ubwino wa madzi, monga momwe zatsimikiziridwa ndi zotsatira za mayeso osungunuka, sichikhudza ubwino wa madzi, palibe "madzi ofiira", chitoliro chofala chomwe chimagwiritsidwa ntchito pogawa madzi. Kusungunuka kwa madzi bwino Chitoliro cha pulasitiki cha PVC-U mosasamala kanthu za kugwiritsa ntchito soketi yamoyo kapena kuphatikiza kwa soketi ya TS, chimakhala ndi kulimba kwabwino kwa madzi, ngakhale kuti kwa zaka zambiri madzi akukakamizidwa kugawa madzi, komanso sichingawononge kutayikira. Kumanga chitoliro chosavuta cha PVC-U chomanga mwachangu komanso mosavuta, mtengo wa ntchito yomanga ndi wotsika.
Chitoliro cha pulasitiki cha PVC-U
Chitoliro cha PVC-U monga chotulutsira madzi, chifukwa cha makhalidwe ake, kugwiritsa ntchito kutentha kwa madzi otuluka mkati mwa nyumba sikuyenera kupitirira 40 ℃, pomwe kutentha kwa madzi otuluka nthawi yomweyo sikuyenera kupitirira 80 ℃. Izi nthawi zambiri zimanyalanyazidwa ndipo zingayambitse kutuluka kwa madzi m'malo olumikiziranamo nthawi yayitali, makamaka m'ma laboratories ena a biochemical m'nyumba za ma laboratories aku yunivesite komwe mavuto otere amapezeka nthawi zambiri. Ndipo yankho lingakhale kungosintha zida zina zachitsulo zotulutsira madzi. Nthawi yomweyo chitoliro cha PVC chiyenera kuyikidwa kuti tipewe kukonza magwero otentha mu annex, zomwe ziyenera kudziwika makamaka pakuyika ngalande za kukhitchini, kuti tiwonetsetse kuti mtunda pakati pa ngalande ndi chitofu, ngati sichoncho, uyenera kutenga njira zotetezera kutentha.


Chitoliro chotulutsira madzi cha PVC-U chikagwiritsidwa ntchito m'nyumba zazitali. Mainjiniya ndi akatswiri ena sachitapo kanthu kuti aletse moto kulowa monga momwe zalembedwera m'malamulo aukadaulo. Njira yolondola ndi iyi: malinga ndi malamulo aukadaulo, chokwezera chimayikidwa poyera ndipo m'mimba mwake wa chitoliro ndi wokulirapo kapena wofanana ndi 110mm~l,-J, pamalo okwezera madzi omwe akudutsa pansi. Ayenera kuchitapo kanthu kuti aletse moto kulowa; m'mimba mwake wa chitoliro chokulirapo kapena chofanana ndi 110mill cha chitoliro chotseguka chodutsa madzi kulowa m'chitsime cha chitoliro, chokwezera madzi, podutsa chitoliro, khoma la dzenje la chitoliro, ayenera kuchitapo kanthu kuti aletse moto kulowa. Main opingasa sayenera kudutsa makoma ogawa moto ndi ma firewall; ngati sizingatheke kutero, njira zoletsera moto ziyenera kutengedwa mbali zonse ziwiri za khoma komwe chitolirocho chimadutsa, monga chivundikiro chosalowa madzi, mphete yozimitsa moto, ndi zina zotero.
