Mumawona "PVC" ndi "uPVC" pamapepala ofotokozera ndipo zikuwoneka kuti zimasinthasintha. Kusokonezeka kumeneku kungayambitse kuyitanitsa zinthu zolakwika pa ntchito yofunika kwambiri, zomwe zingachititse kuti makina azilephera kugwira ntchito bwino.

Pa mapaipi, zolumikizira, ndi ma valve, uPVC (Unplasticized Polyvinyl Chloride) ndi yabwino chifukwa ndi yolimba komanso yolimba. PVC ndi mawu wamba, koma nthawi zambiri amatanthauza pulasitiki yosinthasintha yomwe si yoyenera kugwiritsidwa ntchito popanikizika.

Ichi ndi chimodzi mwa zinthu zomwe zimasokoneza kwambiri makampani athu, ndipo ndi chinthu chofunikira kwambiri. Ndikamalankhula ndi anzanga monga Dumisani ku South Africa, nthawi zonse ndimagogomezera kufunika kwa mawu omveka bwino. Zoona zake n'zakuti, anthu ambiri mumakampaniwa amati “PVC” pomwe kwenikweni amatanthauza “uPVC.” Monga wopanga, ndikukhulupirira kuti ndi udindo wanga kufotokoza izi. Kumvetsetsa kusiyana kumeneku kumathandiza Dumisani kutsogolera makasitomala ake kuti apange chisankho choyenera, kuonetsetsa kuti ntchito iliyonse ndi yotetezeka komanso yopambana. Tiyeni tikambirane mwachidule.

Kodi uPVC ndi yokwera mtengo kuposa PVC?

Mukugwira ntchito ndi bajeti yochepa. Muyenera kudziwa ngati kusankha uPVC kudzawonjezera kwambiri ndalama zomwe zimagwiritsidwa ntchito pa projekiti, kapena ngati kusiyana kwa mitengo kuli kochepa kwambiri moti simungadandaule nako.

Zipangizo zopangira uPVC yolimba ndi PVC yosinthasintha zimakhala ndi mtengo wofanana kwambiri. Mtengo wa chinthucho umadalira kwambiri mtundu, makulidwe a khoma, ndi mbiri ya mtundu wake kuposa kusiyana pakati pa "uPVC" ndi "PVC".

Funso ili limabwera chifukwa cha zomwe zimatsimikiza mtengo womaliza wa valavu kapena cholumikizira. Sizikunena za "u" mu uPVC. Polima yoyambira ndi yomweyi. Zoyendetsa mtengo weniweni ndiubwino wa zosakanizandinjira yopangiraValavu "yotsika mtengo" ndi yotsika mtengo pazifukwa zina, ndipo sikugwirizana ndi mtundu wa PVC yomwe imagwiritsidwa ntchito.

Mtengo wa Zinthu Zofunika Poyerekeza ndi Mtengo wa Zinthu Zofunika

Ku Pntek, ma valve athu onse opanikizika ndizolumikiziraamapangidwa kuchokera ku uPVC. Mukawona kusiyana kwa mtengo pakati pa malonda athu ndi njira ina yotsika mtengo, ndi chifukwa cha zinthu izi, osati chifukwa cha zinthu zoyambira zokha.

Mtengo Wokhudza Zinthu	Njira Yotsika Mtengo Yodziwika Kwambiri	Njira Yapamwamba ya Pntek
Gwero la Zinthu Zopangira	Zipangizo zobwezerezedwanso za utomoni kapena zodzaza	Utomoni wa 100% Virgin uPVC

Chifukwa chake, valavu ya uPVC yabwino ingakhale yokwera mtengo kuposa valavu yotsika mtengo yopangidwanso ndi uPVC. Funso la wogula ngati Dumisani silikunena za uPVC poyerekeza ndi PVC, koma ndi la mtengo wabwino poyerekeza ndi wotsika.

Ndi iti yomwe ili bwino, uPVC kapena PVC?

Muyenera kusankha chinthu choyenera pa payipi yamadzi. Njira imodzi imabweretsa dongosolo lolimba komanso lokhalitsa, pomwe ina ingayambitse kutuluka kwa madzi, kufutukuka, komanso kulephera.

Pakugwiritsa ntchito mphamvu monga mapaipi ndi ma valve, uPVC ndiye chisankho chabwino komanso cholondola. Kulimba kwake ndikofunikira kuti muchepetse mphamvu. PVC yosinthasintha imakhala bwino pokhapokha ngati mukufuna kuti chinthucho chipindike, ngati payipi.

Kunena kuti chimodzi ndi "chabwino" kuli ngati kufunsa ngati nyundo ndi yabwino kuposa screwdriver. Ndi zida zosiyanasiyana zogwirira ntchito zosiyanasiyana. Kusokonezeka kulipo chifukwa chakuti mayinawo ndi ofanana kwambiri. "U" mu uPVC imayimira unplasticized. Izi zikutanthauza kuti sitinawonjezere mankhwala otchedwa plasticizers. Popanda iwo, zinthuzo zimakhala zolimba komanso zolimba.

Chida Choyenera pa Ntchitoyi

Mukawonjezera mapulasitiki, mumapeza PVC yosinthasintha. Izi zimagwiritsidwa ntchito pazinthu zomwe zimafunika kupindika. Pa ntchito iliyonse yomwe imasunga kuthamanga kwa madzi ndipo imafunika kusunga mawonekedwe ake,uPVCndiyo njira yokhayo.

Kugwiritsa ntchito	Zinthu Zabwino Kwambiri	Chifukwa Chake Ndi Bwino
Mzere Waukulu wa Madzi	uPVC	Mphamvu yake ndi kulimba kwake ndizofunikira kuti zichepetse kupanikizika popanda kufutukuka kapena kuphulika.
Paipi ya Munda	PVC yosinthasintha	Kusinthasintha ndiye chinthu chofunikira kwambiri. Paipi yolimba singakhale yopanda ntchito konse.
Thupi la Valavu ya Mpira	uPVC	Iyenera kusunga mawonekedwe ake enieni pansi pa kukakamizidwa kuti iwonetsetse kuti mpira wamkati ndi mipando zikutsekedwa bwino.

Kwa makasitomala a Dumisani omwe ndi makontrakitala ndi omanga, yankho lake ndi losavuta: mukufunika uPVC ya mapaipi anu onse, zolumikizira, ndi ma valve. Ku Pntek, ndicho chomwe timachita bwino kwambiri—zinthu zapamwamba kwambiri za uPVC zoyendetsera madzi.

Kodi mavuto a mapaipi a uPVC ndi ati?

Mukupangira uPVC pa ntchito yaikulu. Kuti mupewe mavuto amtsogolo ndikusunga mbiri yanu, muyenera kukhala oona mtima za zofooka ndi zofooka za zinthuzo musanayambe ntchito.

Zoyipa zazikulu za uPVC ndi kufooka kwa kutentha kozizira komanso kuwonongeka chifukwa cha kuwala kwa dzuwa kwa nthawi yayitali. Sizingagwiritsidwenso ntchito pamadzi otentha, chifukwa zimafewa ndikutaya mphamvu yake.

Palibe chinthu changwiro, ndipo wogulitsa wabwino nthawi zonse amakhala woona mtima pankhani ya zofooka za chinthucho. Kudalirana kumamangidwa pa kuwonekera poyera. Ngakhale uPVC ndi chinthu chodabwitsa, ndikofunikira kudziwa komwe sichiyenera kugwiritsidwa ntchito, komanso momwe mungachitetezere.

Kumvetsetsa Zofooka za uPVC

Nazi zinthu zitatu zomwe muyenera kuganizira:

1. Kusalimba kwa Kutentha Kochepa:Mu nyengo yozizira kwambiri, chitoliro cha uPVC kapena valavu zimatha kusweka. Kugundana kwakukulu ndi fosholo kapena galimoto kungayambitse kusweka. Izi sizodetsa nkhawa kwenikweni m'nyengo yotentha ngati Indonesia, koma ndichifukwa chake makina m'madera ozizira ayenera kubisika pansi pa mzere wozizira kapena kusungidwa bwino m'nyengo yozizira.
2. Kuzindikira kwa UV:Ichi ndiye chinthu chofunikira kwambiri pakupanga zinthu panja. Kuwonekera mwachindunji komanso kwa nthawi yayitali padzuwa kudzawononga uPVC. Imasintha mtundu wake ndikusweka. Pachifukwa ichi, mapaipi akunja ayenera kupakidwa utoto wa latex wopangidwa ndi madzi kapena kubisika. Timawonjezera zoletsa za UV ku fomula yathu kuti tichepetse izi, koma chitetezo chakuthupi nthawi zonse ndiye njira yabwino kwambiri yogwiritsira ntchito nthawi yayitali.
3. Malire a Kutentha:UPVC wamba (Ndandanda 40/80) sayenera kugwiritsidwa ntchito pamizere yamadzi otentha. Zipangizozo zimayamba kufewa pamwamba pa 140°F (60°C). Zikafewa, zimataya mphamvu yake yogwira mphamvu. Pamadzi otentha, pulasitiki yoyenera kugwiritsa ntchito ndi CPVC (Chlorinated Polyvinyl Chloride).

Kodi PVC yothamanga kwambiri ndi yabwino kuposa uPVC?

Mukuwona mawu monga “Konzani 80″ kapena “PVC yothamanga kwambiri.” Mukuganiza ngati iyi ndi chinthu chatsopano, cholimba chomwe chili chosiyana ndi uPVC yomwe mukuyidziwa kale.

"PVC yothamanga kwambiri" ndi dzina chabe la chitoliro cha uPVC chokhala ndi makoma okhuthala, nthawi zambiri Ndondomeko 80. Si chinthu china. Chidakali uPVC, koma makulidwe ake owonjezera amalola kuti chizitha kuthana ndi kupsinjika kwamkati kwambiri.

Ichi ndi chinthu china chomwe chikusokoneza kwambiri msika. "PVC yothamanga kwambiri" ndi "uPVC" si zinthu ziwiri zosiyana zomwe mungasankhe. Chitoliro chothamanga kwambiri chimapangidwa kuchokera ku uPVC. Kutha kuthana ndi kupanikizika kumatsimikiziridwa ndi makulidwe a khoma. Makampani amagwiritsa ntchito nambala ya "Ndondomeko" kuti afotokoze izi.

Kuyeza kwa Kupanikizika ndi Kunenepa, Osati Zinthu Zapadera

Mapaipi onse a Schedule 40 ndi Schedule 80 amapangidwa kuchokera ku zinthu zomwezo za uPVC. Kusiyana kokha ndi kuchuluka kwa zinthu zomwe zagwiritsidwa ntchito. Taganizirani ngati bokosi lopyapyala la makatoni poyerekeza ndi lokhuthala; onse ndi makatoni, koma limodzi ndi lolimba kwambiri.

Kasitomala akapempha Dumisani kuti amupatse "PVC yothamanga kwambiri," kwenikweni amangopemphaNdondomeko 80 uPVC"Zimakhala bwino" kokha ngati kukakamizidwa kwa pulogalamuyo kukufuna. Pogwiritsa ntchito Sch 80 pomweSch 40zokwanira ndi zotetezeka, komanso zodula kwambiri.

Mapeto

uPVC ndi chinthu cholimba komanso cholimba chomwe chimagwiritsidwa ntchito popangira mapaipi opanikizika komansomavavuNgakhale kuti nthawi zambiri amatchedwa "PVC", kumvetsetsa kuti uPVC ndiye chisankho choyenera kumachotsa chisokonezo ndikutsimikizira kudalirika kwa makina.
