Chimodzi mwa zinthu zazikulu kwambiri m'mbiri ya anthu chinali kubwera kwa mapaipi amkati. Mapaipi amkati akhala padziko lonse lapansi kuyambira m'ma 1840, ndipo zipangizo zosiyanasiyana zagwiritsidwa ntchito popereka mipanda ya mapaipi. M'zaka zaposachedwapa, mapaipi a PVC akhala otchuka kwambiri kuposa mapaipi amkuwa monga chisankho choyamba cha mapaipi amkati. PVC ndi yolimba, yotsika mtengo, komanso yosavuta kuyiyika, zomwe zimapangitsa kuti ikhale imodzi mwa njira zabwino kwambiri zopangira mapaipi.

Ubwino wogwiritsa ntchito PVC m'mapaipi
Mapaipi a PVC akhalapo kuyambira cha m'ma 1935 ndipo anayamba kugwiritsidwa ntchito ngati mapaipi otulutsa madzi, zinyalala, ndi mpweya wabwino panthawi yomanganso pambuyo pa Nkhondo Yachiwiri Yapadziko Lonse. Kuyambira nthawi imeneyo, akhala otchuka kwambiri ndipo akhala chisankho chodziwika bwino cha mapaipi padziko lonse lapansi. Ndipo, ngakhale kuti tingakhale ndi tsankho pang'ono, n'zosavuta kuona chifukwa chake zili choncho.

PVC ndi imodzi mwa zipangizo zotsika mtengo kwambiri pamsika masiku ano. Sikuti ndi yopepuka, yolimba komanso yosavuta kuyika.Chitoliro cha PVCimatha kupirira kutentha mpaka 140° ndipo imatha kupirira kupsinjika mpaka 160psi. Ponseponse, ndi chinthu cholimba kwambiri. Ndi cholimba komanso chosagwira ntchito ndi mankhwala ndipo imatha kupirira nyengo zosiyanasiyana. Zonsezi zimapangitsa PVC kukhala chinthu cholimba chomwe chingakhalepo kwa zaka pafupifupi 100. Kuphatikiza apo, kusintha kosachitika kawirikawiri kumeneku kumathandiza kuchepetsa kuwonongeka kwa chilengedwe.

CPVC ndi CPVC CTSmu Mapaipi a Nyumba
Monga tanenera, timakonda pang'ono PVC, koma sizikutanthauza kuti sitizindikira zinthu zina zodabwitsa tikamaziona - zomwe ndi CPVC ndi CPVC CTS. Zogulitsa zonsezi ndi zofanana ndi PVC, koma zili ndi ubwino wake.

CPVC ndi PVC yokhala ndi chlorine (apa ndi pomwe C yowonjezera imachokera). CPVC imayikidwa pa 200°F, zomwe zimapangitsa kuti ikhale chisankho choyamba chogwiritsa ntchito madzi otentha. Monga chitoliro cha PVC, CPVC ndi yosavuta kuyika, yolimba ndipo siifuna kukonza kwambiri.

PVC ndi CPVC zonse zimagwiritsa ntchito tchati cha kukula komweko, chomwe sichigwirizana ndi chitoliro cha mkuwa. Kwa zaka zambiri za m'ma 20 ndi kumayambiriro kwa zaka za m'ma 2000, chitoliro cha mkuwa chinali chitoliro chomwe chinkagwiritsidwa ntchito kwambiri popangira mapaipi. Simungagwiritse ntchito PVC kapena CPVC mu mzere wanu wa chitoliro cha mkuwa chifukwa cha mitundu yosiyanasiyana ya kukula, ndi pomwe CPVC CTS imabwera. CPVC CTS ndi CPVC mu kukula kwa chitoliro cha mkuwa. Mapaipi awa amapangidwa ngati CPVC ndipo angagwiritsidwe ntchito ndi mapaipi amkuwa ndi zolumikizira.

Chifukwa chiyani muyenera kugwiritsa ntchito chitoliro cha PVC
Kukonza mapaipi ndi gawo lofunika kwambiri panyumba kapena bizinesi iliyonse, ndipo kumawononga ndalama zambiri. Pogwiritsa ntchito mapaipi a PVC, mutha kudzipulumutsa nokha ku zokonza zokwera mtengo komanso mtengo woyambira wa mapaipi achitsulo. Chifukwa cha kukana kutentha, kupanikizika ndi mankhwala, ndalama zake zidzakhalapo kwa moyo wonse.
