1. Cov khoom siv sib txawv
Cov yeeb nkab pe yog cov yeeb nkab polyethylene uas feem ntau hais, thiab cov yeeb nkab ppr yog peb hom polypropylene yeeb nkab, uas kuj yog cov khoom hloov kho ntawm cov yeeb nkab PE, thiab cov elasticity ntawm cov yeeb nkab ppr ib txwm zoo dua li cov yeeb nkab PE. cev.
2. Txawv thermal conductivity
Cov thermal conductivity ntawm cov kav dej pe yog zoo dua li cov kav dej ppr. Lub thermal conductivity ntawm pe kav yog 0.42, uas yog ib tug high class. Zoo sib xws hauv cov ntsiab lus, tab sis qhov kub tsis tshua muaj siab ntawm pe raj yog zoo dua li ntawm lub raj ppr.
3. Txawv vuam kev ua tau zoo
Cov yeeb nkab ppr yooj yim dua rau vuam dua li cov yeeb nkab pe, thiab thaum cov yeeb nkab pe welded, yog tias qhov kev kho tsis nyob hauv qhov chaw, yuav muaj teeb meem ntawm kev thaiv thiab xau, thiab xav txog cov khoom specifications, cov yeeb nkab txoj kab uas hla ntawm pe. cov yeeb nkab feem ntau yog khaws cia ntawm 20 mus rau 300 hli Qhov txoj kab uas hla ntawm PPR yeeb nkab yog me dua, feem ntau ntawm 20 thiab 100 hli.
4. Cov nqi sib txawv / kev ua tau zoo
Txawm hais tias ob hom kav dej muaj ntau heev hauv lub neej niaj hnub, tom qab kev txiav txim siab zoo, cov nqi ntawm cov kav dej ppr yuav tsum yog cov kav dej pe, thiab nws kuj yog ib hom yeeb nkab khoom siv ntau dua hauv kev kho kom zoo nkauj hauv tsev, vim tias cov kav dej pe yog feem ntau siv hauv cov kav dej. cov kav dej thiab cov kav dej. Txawm siv cov yeeb nkab dej twg, nws yuav tsum tau xaiv raws li qhov chaw tsim kho thiab nws tus kheej xav tau.
