PIR (polyisocyanurate) thiab PUR (polyurethane) sandwich vaj huam sib luag paub txog lawv cov kev ua tau zoo ntawm kev rwb thaiv tsev thiab hluav taws kub, yog li tau xaiv dav rau cov haujlwm xws li cia txias. Cov tub ntxhais ua npuas ncauj ua lub luag haujlwm tseem ceeb hauv kev rwb thaiv tsev thiab hluav taws kub ua haujlwm. Tab sis koj puas paub tias kev xaiv ntawm cov khoom siv saum npoo kuj tseem ceeb thiab tuaj yeem ntxiv cov haujlwm ntxiv rau cov sandwich panels.
Ib qho ntawm cov khoom siv nrov tshaj plaws yog PPGI: PPGI, lossis Preprinted Galvanized Iron, yog cov khoom siv hlau ntau yam siv dav hauv kev tsim kho thiab tsim khoom. Nws nta ib lub hauv paus galvanized steel uas yog coated nrog ib txheej xim rau zoo heev corrosion kuj thiab durability. Cov yam ntxwv tseem ceeb suav nrog nws qhov hnyav hnyav thiab nws muaj nyob hauv ntau yam xim thiab ua tiav rau kev kho kom zoo nkauj. PPGI kuj yog ib puag ncig zoo heev vim nws cov txheej txheem tsim khoom tsim tawm tsawg dua. PPGI muaj lub neej ua haujlwm ntev thiab kev saib xyuas tsawg, ua rau nws zoo tagnrho rau vov tsev, phab ntsa cladding thiab lwm yam kev siv.
Feem ntau, PPGI steel nto tuaj yeem ntxiv kev tiv thaiv corrosion, lub zog thiab dej tsis zoo rau PIR sandwich vaj huam sib luag thiab PUR sandwich vaj huam sib luag hauv kev siv txias cia. Thiab nrog ntau thiab customizable xim, lawv kuj muaj ib tug txaus nyiam tsos.
Lwm cov khoom siv hlau nto npe nrov yog cov hlau tsis muaj steel, cov hlau tsis muaj steel ua tau zoo dua ntawm lub zog, thiab SUS304 stainless hlau zoo dua ntawm kev tiv thaiv corrosion. Tsis tas li ntawd, cov hlau tsis muaj steel muaj qhov tshwj xeeb ci ntsa iab ua rau lub vaj huam sib luag sandwich zoo li siab kawg.
Dhau li ntawd, lwm yam khoom siv saum npoo zoo li customized alloy, aluminium kuj tseem xaiv rau kev siv tshwj xeeb, xws li zaub mov zoo lossis super siab corrosion kuj.
Dhau li ntawm cov khoom siv hlau nws tus kheej, cov txheej kuj tuaj yeem pab nrog cov yam ntxwv tshwj xeeb.
Txheej txheej muaj xws li:
1. PVDF (Polyvinylidene Fluoride): Paub txog nws qhov tshwj xeeb tiv thaiv UV hluav taws xob, tshuaj lom neeg, thiab huab cua, PVDF muab cov glossy tiav uas khaws cov xim vibrancy dhau sijhawm. Qhov no ua rau nws zoo tagnrho rau kev siv sab nraum zoov, tshwj xeeb tshaj yog nyob rau hauv architectural tej yaam num.
2. HDP (High-Durability Polyester): HDP coatings muaj superior durability thiab khawb kuj, ua rau lawv haum rau high-tsheb thauj mus los thiab muaj ib puag ncig. Lawv tiv thaiv corrosion thiab ib puag ncig yam, ncua lub neej ntawm cov khoom.
1.EP (Epoxy Polyester): Cov txheej txheej no sib xyaw cov txiaj ntsig ntawm epoxy thiab polyester, muab cov adhesion zoo heev thiab ua haujlwm rau cov tshuaj thiab dej noo. EP txheej yog qhov zoo tagnrho rau kev siv sab hauv tsev thiab ib puag ncig uas muaj tshuaj lom neeg muaj kev txhawj xeeb.
Kev xaus, qhov kev xav tau sib txawv tuaj yeem txaus siab los ntawm cov khoom siv sandwich sib txawv rau ob qho tib si PIR thiab PUR sandwich vaj huam sib luag. Thov hu rau peb nrog cov lus nug tshwj xeeb, peb yuav pab koj nrhiav kev daws teeb meem zoo tshaj plaws rau koj lub tub yees txias.
