PP-R yeeb nkab tseem raug hu ua peb hom polypropylene yeeb nkab, raw cov ntaub ntawv tsuas yog carbon thiab hydrogen molecules, tsis tsim teeb meem tshuaj lom neeg, kev noj qab haus huv thiab kev cia siab, tsis yog rau cov kav dej kub thiab dej txias, tiam sis kuj rau cov dej ntshiab haus. .PPR tooj liab puab txheej yog tooj, thiab saum npoo yog PPR.PPR coated txhuas tube, nrog ib PPR. txheej.
Dej kub yog kwv yees li 60 degrees, thiab lub neej kev ua haujlwm muaj peev xwm tshaj 50 xyoo.
Tab sis Cov Tsev Neeg Zoo li cas tsev neeg siv tsev neeg?
Feem ntau, muaj 20, 25, 32, peb yam lus, uas txaus, S3.2 thiab S2.5 cov kav dej kub. Cov ob hom no yog cov kav dej kub siv rau tsev neeg. Lawv muaj PPR txuj thiab PPR tua kab mob. Yog tias lawv raug siv rau cua sov, lawv yuav siv tus qauv PPR. S4 thiab S5 yog kav dej kub thiab dej txias. Feem ntau siv 4 pawg (inch 25 hli, thickness hauv 3.4mm), kev siv cov dej kub xa, PPR yeeb nkab C yeeb nkab, B yeeb nkab, feem ntau yog hais txog kev ua haujlwm kub.
