Cov khoom sib txawv ntawm PERT thiab tooj liab
PERT (heat-resistant polyethylene) yog siab-kub resistant cov tswv cuab ntawm cov yas tsev neeg, nrog ib tug melting point ntawm kwv yees li 120-140 degree, thaum tooj liab muaj ib tug melting point siab txog 1083 degree. Ob leeg zoo li dej khov thiab hlau-ib qho yog cua sov-sensitive, lwm yam kub-resistant. Thaum fused ncaj qha, PERT yuav tau vaporized thiab decomposed, thaum tooj liab yuav tsis txawm pib muag.
Cov Kev Sib Txuas Ua Tau Zoo
Txawm hais tias kev sib txuas ncaj qha tsis ua tau, engineers muaj cov kev daws teeb meem ntse:
Kev hloov pauv cov pob qij txha: Siv PERT fittings nrog tooj liab inserts, ua tiav lub foob los ntawm kev siv tshuab crimping.
Thaum tshav kub kub- Melt Flanges: Thaum tshav kub kub- melted ib tug yas flange ntawm PERT kawg, ces ntsia liaj qhov rooj rau tooj liab flange.
Adhesive Technology: Cov nplaum tshwj xeeb muab kev ruaj khov ntawm qhov kub hauv qab 80 degree.
Daim ntawv thov Scenarios thiab ceev faj
PERT thiab tooj liab kav feem ntau siv ua ke hauv cov dej kub thiab txias, tab sis cov hauv qab no yuav tsum tau muab sau tseg:
Kev hloov pauv kub tuaj yeem ua rau qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv sib txawv (PERT qhov nthuav dav yog 10 npaug ntawm tooj liab).
Electrochemical Corrosion Risk: Insulating gaskets yuav tsum tau tiv thaiv kev sib cuag ntawm tooj liab thiab PERT.
Rau kev khiav hauj lwm siab tshaj 1.6 MPa, tag nrho cov - hlau txuas tau pom zoo.
