Saj thiab tsw hloov raws li tib lub logic. Silicone muaj qhov zoo ntawm cov qauv vim nws tuav tsis muaj plasticizer uas tuaj yeem txav mus rau hauv cov zaub mov muaj roj. Ib qho zoo silicone tseem tuaj yeem nqa cov ntxhiab tsw yog tias tom qab kho tsis tiav, thiab PP zoo tuaj yeem tsw nruab nrab thaum xaiv qib zoo.
Sealing thiab Mechanical Cwj Pwm
Sealing yog qhov uas ob cov ntaub ntawv sib txawv feem ntau hauv cov ntsiab lus tsim.
Silicone yog elastomer. Nws deforms nyob rau hauv load thiab rov qab. A 40 mus rau 60 Shore Ib lub hau silicone lub nplhaib tsim lub cev foob tiv thaiv lub npoo los yog lub raj mis caj dab nrog tsawg kawg nkaus clamp quab yuam. Qhov no yog vim li cas silicone muaj lub gasket, lub nplhaib hau thiab spout foob qeb.
PP yog nruj. Nws seals tsuas yog los ntawm kev cuam tshuam nyuaj, xov kaw nrog lub zog torque, lossis ntxiv elastomer gasket. Lub hau PP nruj ntawm lub cev PP nruj nyob ntawm cov xov thiab cov phab ntsa thickness ntau dua li ntawm cov khoom ua raws, uas yog vim li cas PP cov thawv ntim khoom xau feem ntau ntawm lub hau interface dua li ntawm lub cev.
Flexibility kuj cuam tshuam rau cov ntaub ntawv siv. Ib lub thawv ntim silicone folds tiaj tus, muaj sia nyob raug poob, thiab rov qab tau nws cov duab. Lub thawv PP yog qhov ruaj khov thiab ruaj khov, uas tseem ceeb rau kev khaws cia ceev thiab kev thauj mus los.
Tus nqi tsim nyog tshaj qhov khoom lub neej
Cov khoom siv tus nqi nyiam PP. Lub thawv PP ntawm tib lub ntim feem ntau raug nqi tsawg dua ntawm cov khoom siv thiab tsawg dua nyob rau hauv lub sijhawm molding lub sij hawm ntau dua li compression molded silicone sib npaug. Qhov sib txawv yuav nqaim los yog thim rov qab thaum daim duab tag nrho suav nrog:
Cov suav suav: lub hau silicone tuaj yeem hloov lub hau PP ntxiv rau ib qho gasket cais, tshem tawm cov kauj ruam sib dhos thiab txoj kev xau
