PPH (homopolymer polypropylene) cov kav dej muaj qhov sib tw kom zoo dua rau ntau qhov laj thawj. Ua ntej, PPH cov hlab ntsha muaj kev tiv thaiv zoo rau kev cuam tshuam thiab tshuaj lom neeg corrosion, ua rau lawv zoo tagnrho rau kev siv hauv qhov chaw hnyav. Qhov kev tiv thaiv no tuaj yeem txo qhov kev xav tau ntawm kev saib xyuas thiab kho, uas ua rau kev txuag nyiaj hauv lub sijhawm ntev.
Qhov thib ob, PPH hlab yog lub teeb yuag thiab hloov tau yooj yim, yooj yim rau nruab, thiab txo cov nqi zog. Lawv kuj tuaj yeem yooj yim folded thiab koom nrog yam tsis tas yuav tsum tau txuas ntxiv. Qhov kev hloov pauv no ua rau PPH cov kav dej yog qhov kev xaiv zoo tshaj plaws rau kev rov qab kho cov tsev uas twb muaj lawm, tshem tawm qhov xav tau kev rov ua dua tshiab.
Tsis tas li ntawd, piv nrog lwm cov kav dej xws li tooj liab thiab stainless hlau, PPH kav dej yog kev lag luam zoo. Lawv muab cov kev xaiv zoo rau cov ntawv thov xws li cov dej kub thiab dej txias, cua tshuab thiab ntau yam kev lag luam. Lawv kuj yog ib puag ncig tus phooj ywg zoo li lawv yog 100 feem pua rov ua dua.
PPH cov kav dej kuj tseem muaj zog heev, nrog rau kev pab cuam lub neej ntawm 50 xyoo lossis ntau dua, ua rau lawv muaj kev xaiv zoo rau kev siv hauv tsev thiab kev lag luam. Lawv tsis xeb, corrode los yog degrade nyob rau lub sij hawm, kom ntseeg tau tias ruaj khov kev ua haujlwm ntev.
Zuag qhia tag nrho, PPH cov kav dej muaj qhov sib tw zoo dua vim lawv qhov zoo, ua haujlwm ntev thiab kev lag luam. Lawv muab cov kev daws teeb meem zoo tshaj plaws rau ntau yam kev siv thiab muab kev ntseeg siab thiab ua haujlwm ntev.
Dab tsi yog qhov tshwj xeeb ntawm cov kav dej PPH piv rau cov khoom siv xws li PVC lossis tooj liab?
PPH (homopolymer polypropylene) cov kav dej muaj ntau qhov zoo dua li cov khoom siv xws li PVC lossis tooj liab. Cov txiaj ntsig no suav nrog:
Corrosion resistance: PPH tubes yog cov tshuaj tiv thaiv zoo rau cov tshuaj, acids thiab lwm yam corrosive agents, ua rau lawv zoo tagnrho rau siv nyob rau hauv ib puag ncig hnyav.
Durability: PPH tubes muaj zog thiab tuaj yeem tiv taus hnyav yam tsis muaj kev tawg lossis tawg. Qhov no txhais tau tias lawv tuaj yeem kav ntev dua thiab xav tau kev saib xyuas tsawg dua li lwm yam khoom siv.
Flexibility: Cov kav dej PPH tau hloov pauv ntau dua li cov kav dej tooj liab thiab yooj yim rau nruab, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam nyuaj.
Dimensional stability: PPH hlab muaj qhov siab ruaj khov, uas txhais tau hais tias lawv tswj lawv cov duab thiab qhov loj me txawm tias nyob rau hauv huab cua txias xws li kub thiab siab. Qhov no txo qhov kev pheej hmoo ntawm cov yeeb nkab deformation thiab tso cai rau tus nqi ntws zoo ib yam.
Txo kev sib txhuam tsis zoo: Cov phab ntsa sab hauv ntawm lub raj PPH yog du kom tiv thaiv cov av nkos, txo kev sib txhuam, txo kev siv zog, thiab txhim kho kev ua haujlwm.
PPH dej yeeb nkab ua haujlwm li cas hauv huab cua huab cua? Qhov no puas ua rau koj qhov kev sib tw zoo dua?
PPH cov kav dej ua haujlwm zoo hauv huab cua huab cua vim tias lawv tiv taus corrosion, tshuaj lom neeg puas tsuaj thiab hluav taws xob UV. Cov raj no muaj qhov kub thiab txias ntawm -40⁰C txog 90⁰C, ua rau lawv haum rau siv ntau yam kev nyab xeeb. Lawv lub zog thiab yoog raws ua rau lawv zoo tagnrho rau huab cua hnyav xws li cua daj cua dub thiab av qeeg. Tsis tas li ntawd, PPH yeeb nkab yog lub teeb yuag thiab yooj yim rau nruab, txo cov nqi zog thiab sijhawm, muab kev sib tw kom zoo dua lwm cov khoom siv yeeb nkab. Nws cov kev tiv thaiv ib puag ncig thiab kav ntev kuj muab nws qhov kev sib tw kom zoo dua.
