Cov qhov tsis zoo ntawm cov kav dej uPVC yog dab tsi?

Koj tab tom pom zoo kom siv uPVC rau ib qho project loj. Yuav kom tsis txhob muaj teeb meem yav tom ntej thiab tswj koj lub koob npe nrov, koj yuav tsum qhia qhov tseeb txog qhov tsis muaj zog thiab kev txwv ntawm cov khoom ua ntej pib ua haujlwm.

Qhov tsis zoo ntawm uPVC yog qhov tsis yooj yim tawg thaum lub caij txias thiab kev puas tsuaj los ntawm kev raug UV (hnub ci) ntev. Nws kuj tsis tuaj yeem siv rau dej kub, vim nws mos thiab poob nws qhov ntsuas siab.

Tsis muaj cov khoom siv twg zoo tag nrho, thiab tus neeg muag khoom zoo yeej ib txwm ncaj ncees txog cov kev txwv ntawm cov khoom. Kev ntseeg siab yog tsim los ntawm kev pob tshab. Txawm hais tias uPVC yog cov khoom siv zoo heev, nws yog ib qho tseem ceeb kom paub tias nws yuav tsum tsis txhob siv qhov twg, thiab yuav tiv thaiv nws li cas.

Nkag Siab Txog Qhov Txwv ntawm uPVC

Nov yog peb yam koj yuav tsum xav txog:

1. Kev Nyuaj Siab Kub Qis:Thaum huab cua txias, cov yeeb nkab uPVC lossis lub qhov dej yuav tawg yooj yim. Kev cuam tshuam los ntawm lub tshuab rab diav lossis lub tsheb tuaj yeem ua rau nws tawg. Qhov no tsis yog qhov txhawj xeeb hauv huab cua sov xws li Indonesia, tab sis nws yog vim li cas cov kab ke hauv thaj chaw txias yuav tsum tau faus rau hauv qab kab te lossis khaws cia rau lub caij ntuj no kom zoo.
2. Kev rhiab heev ntawm UV:Qhov no yog qhov tseem ceeb tshaj plaws rau kev teeb tsa sab nraum zoov. Kev raug tshav ntuj ncaj qha, ntev ntev yuav ua rau uPVC tawg. Nws yuav ploj xim thiab tawg yooj yim. Vim li no, cov kav dej sab nraum zoov yuav tsum tau pleev xim nrog cov xim latex uas yog dej lossis faus rau hauv av. Peb ntxiv cov tshuaj tiv thaiv UV rau hauv peb cov mis kom qeeb cov txheej txheem no, tab sis kev tiv thaiv lub cev yeej ib txwm yog txoj hauv kev zoo tshaj plaws rau lub sijhawm ntev.
3. Kev Txwv Kub:Tsis txhob siv cov uPVC txheem (Daim Ntawv Teev Npe 40/80) rau cov kav dej kub. Cov khoom siv pib mos dua 140°F (60°C). Thaum nws mos, nws poob nws lub peev xwm tuav qhov siab. Rau cov dej kub, cov yas zoo siv yog CPVC (Chlorinated Polyvinyl Chloride).

Puas yog PVC siab siab zoo dua li uPVC?

Koj pom cov lus zoo li "Schedule 80" lossis "high-pressure PVC." Koj xav tsis thoob tias qhov no puas yog cov khoom siv tshiab, muaj zog dua uas txawv ntawm uPVC uas koj twb paub lawm.

"PVC siab" tsuas yog lub npe rau cov yeeb nkab uPVC uas muaj phab ntsa tuab dua, feem ntau yog Schedule 80. Nws tsis yog lwm yam khoom siv. Nws tseem yog uPVC, tab sis nws qhov tuab ntxiv tso cai rau nws los tswj cov kev nyuaj siab sab hauv siab dua.

Qhov no yog lwm qhov ua rau muaj kev tsis meej pem loj hauv kev ua lag luam. "PVC siab" thiab "uPVC" tsis yog ob yam khoom sib txawv los xaiv. Cov yeeb nkab siab yog ua los ntawm uPVC. Lub peev xwm los tswj kev siab yog txiav txim siab los ntawm phab ntsa tuab. Kev lag luam siv tus lej "Schedule" los txhais qhov no.

Kev Ntsuas Siab yog Hais Txog Qhov Thickness, Tsis Yog Khoom Siv

Ob lub kav dej Schedule 40 thiab Schedule 80 yog ua los ntawm tib yam khoom siv uPVC. Qhov txawv tsuas yog qhov ntau ntawm cov khoom siv. Xav txog nws zoo li lub thawv ntawv nyias dua li lub thawv tuab; ob qho tib si yog ntawv cardboard, tab sis ib qho muaj zog dua.

Feature	Teem sijhawm 40 uPVC	Teem Caij 80 uPVC ("Kev Siab Siab")
Hom Khoom Siv	uPVC	uPVC (cov khoom siv tib yam)
Phab ntsa tuab	Nyias dua	Tuab dua
Kev Ntsuas Siab	Qis dua	Siab dua

Kev Siv Tseem Ceeb	DWV nyob hauv tsev, kev ywg dej qis	Cov kab ua haujlwm hauv kev lag luam, cov kav dej siab

Thaum ib tug neeg siv khoom nug Dumisani txog "high pressure PVC," lawv tsuas yog nug xwbTeem sijhawm 80 uPVCNws tsuas yog "zoo dua" yog tias daim ntawv thov lub siab xav tau nws. Siv Sch 80 qhov twgSch 40txaus lawm thiab muaj kev nyab xeeb, tab sis nws kuj kim heev tsis tsim nyog.
