Yuav ua li cas txheeb qhov zoo thiab tsis zoo ntawm PTC cov ntaub ntawv rau hluav taws xob cua sov cable?

PTC cov khoom yog cov khoom tseem ceeb tshaj plaws hauv kev tsim cov hluav taws xob cua kub cab. Nws feem ntau yog hais txog sandiconductor cov ntaub ntawv lossis cov khoom siv nrog qhov kub thiab txias hnyav. PTCs feem ntau yog hu ua cov cua sov uas zoo. Raws li qhov kub ambient kub tsawg dua, qhov tsis kam ntawm PTC txo qis, thaum nws cov huab cua kub nce ntxiv. Cov khoom ptc no, thaum siv hauv hluav taws xob cua sov cable, tso cai rau lawv kom ua tiav qhov kev tswj kub zoo nyob hauv lub sijhawm luv tshaj plaws. Qhov zoo tshaj ntawm PTC cov khoom tuaj yeem txiav txim siab qhov zoo ntawm kev sib txuas cable. Ntawm no yog yuav ua li cas paub qhov txawv nws.
... 3.} combusionation kuaj: Ua rau PTC tseem ceeb ntawm cov cua kub cable rau ib qho chaw qhib. Tsis - Cov ntaub ntawv yog suav tias yog qhov zoo dua qub, thaum nplaim taws} retammable cov ntaub ntawv yog suav tias yog qis dua qis dua. Txawm li cas los xij, halogen -} muaj nplaim taws - retardant cov ntaub ntawv yuav tsum txwv. Thaum Flame - retardant, halogen -}}}}}}}}}}}}}}, ua rau lawv muaj kev phom sij ntau dua li cov khoom siv hluav taws xob. Hauv lwm lo lus, thaum nplaim taws - retardant, lawv suav hais tias muaj hnub nyoog thiab tsis {{ib puag ncig zoo.

4. Qhov muag muag thiab tawv ncauj thiab tawv: cov ntaub ntawv nrog ntau dua hardness feem ntau muaj qhov ntom ntau dua thiab tus nqi. Piv txwv, qis - qhov ceev polyethylene (LDPE) yog qhov ntsuas kub thiab tsis xav tau Rauv Hla {4} ° C. Siab - ntom polyethylene (HDPE) yog qhov nyuaj ntawm 90 ° C Tom qab Rauv Hla-}-}} Qhov zoo ntawm cov khoom yog txiav txim siab los ntawm nws cov kev ua tau zoo.
