Nchifukwa chiyani magolovesi a PVC sangatsukidwe?

Magolovesi a PVC amagwiritsidwa ntchito kwambiri m'makampani ndi m'moyo watsiku ndi tsiku, koma sayenera kutsukidwa ndi ukhondo, zomwe zimatsimikiziridwa makamaka ndi zinthu zawo ndi mawonekedwe awo.

Ponena za zinthu, magolovesi a PVC amapangidwa makamaka ndi polyvinyl chloride resin, yomwe ndi polima ya molekyulu yambiri. Zinthuzi sizimakhazikika pa mankhwala. Panthawi yoyeretsa, makamaka pogwiritsa ntchito njira yotsukira yokhala ndi sopo wa mankhwala, zigawo za mankhwala zomwe zili mu sopo zimatha kuchita mankhwala ndi polyvinyl chloride. Mwachitsanzo, sopo wina wa alkaline amawononga kapangidwe ka molekyulu ka polyvinyl chloride, zomwe zimapangitsa kuti magolovesi akhale olimba komanso ofooka, ndikutaya kusinthasintha kwawo koyambirira komanso kusinthasintha, motero zimakhudza magwiridwe antchito ndi moyo wa magolovesi. Ngakhale sopo wofewa wochepa atagwiritsidwa ntchito, kuyeretsa kwa nthawi yayitali kungayambitse zowonjezera monga pulasitiki pamwamba pa magolovesi kuti zigwe, kusintha mawonekedwe a magolovesi.

Ponena za kapangidwe kake, pamwamba pa magolovesi a PVC sipakhala powundana kwathunthu komanso mofanana. Pali ma pores ambiri ang'onoang'ono ndi zinthu zosafanana pamwamba pake, zomwe zimakhala zosavuta kuyamwa fumbi, mafuta ndi zonyansa zina mukamagwiritsa ntchito. Poyeretsa, ngakhale kuti dothi lina pamwamba pake lingachotsedwe, zonyansa zomwe zili mkati mwa ma pores zimakhala zovuta kuzichotsa kwathunthu. Kuphatikiza apo, mphamvu ya kuyenda kwa madzi ndi kukangana kwa makina panthawi yoyeretsa zitha kukulitsa ma pores awa, zomwe zimapangitsa kuti zonyansa zambiri zitsale, zomwe zimachepetsa ukhondo wa magolovesi.

Kuphatikiza apo, popanga magolovesi a PVC, kuti akwaniritse zofunikira zinazake zogwirira ntchito, zowonjezera zosiyanasiyana, monga zokhazikika, mafuta odzola, ndi zina zotero, zimawonjezedwa. Zowonjezera izi zitha kusungunuka kapena kusungunuka panthawi yoyeretsa, zomwe zingadetse madzi oyeretsera ndikukhudza momwe amayeretsera mbali imodzi; kumbali ina, kutayika kwa zowonjezera kudzasintha magwiridwe antchito a magolovesi ndikuchepetsa mphamvu zawo zoteteza.

Poganizira momwe magolovesi a PVC amagwiritsidwira ntchito, magolovesi a PVC nthawi zambiri amakhala magolovesi otayidwa, ndipo kapangidwe koyambirira kake ndi kokwanira kukwaniritsa zosowa za kugwiritsidwa ntchito kamodzi kokha, ndipo mtengo wake ndi wotsika. Kuyeretsa ukhondo kumafuna anthu ambiri, zinthu zakuthupi komanso ndalama zogulira nthawi, ndipo zotsatira zake zimakhala zovuta kutsimikizira mutatsuka. Magolovesi akagwiritsidwanso ntchito mutatsuka, magwiridwe antchito ndi chitetezo cha magolovesiwo chachepa kwambiri ndipo sichingakwaniritse zofunikira pakugwiritsa ntchito. Mosiyana ndi zimenezi, ndikosavuta komanso kosavuta kusintha magolovesi atsopano a PVC mwachindunji.
