Umahluko phakathi kwePVC ethambileyo kunye nePVC enzima

I-PVC inokohlulwa ibe zizixhobo ezimbini: i-PVC eqinile kunye ne-PVC ethambileyo. Igama lenzululwazi lePVC yipolyvinyl chloride, eyona nxalenye iphambili yeplastiki kwaye iqhele ukusetyenziswa ukwenza iimveliso zeplastiki. Ixabiso eliphantsi kwaye lisetyenziswa ngokubanzi. I-akhawunti ye-PVC enzima malunga nesibini kwisithathu semarike, ngelixa i-PVC ethambileyo ithatha isinye kwisithathu. Ke, yintoni umahluko phakathi kwePVC ethambileyo kunye nePVC enzima?

1. Amanqanaba ahlukeneyo okuthamba kunye nobunzima

Owona mahluko mkhulu kubunzima bazo obahlukeneyo. I-PVC enzima ayinazo izinto ezithambileyo, inokuguquguquka okuhle, kulula ukuyibumba, kwaye ayibi brittle ngokulula, ayinayo ityhefu kunye nongcoliseko, inexesha elide lokugcina, kwaye inophuhliso olukhulu kunye nexabiso lesicelo. I-PVC ethambileyo, kwelinye icala, iqulethe izinto ezithambileyo ezinokuthamba okuhle, kodwa ithanda ukuba brittleness kunye nobunzima ekugcinweni, ngaloo ndlela ukusebenza kwayo kulinganiselwe.

1. Iuluhlu lwezicelozahlukile

Ngenxa yokuguquguquka okuhle, iPVC ethambileyo isetyenziswa ngokubanzi kumphezulu wamalaphu etafile, imigangatho, iisilingi, kunye nethwathwa; I-polyvinyl chloride enzima isetyenziswa ikakhulu kwimibhobho eqinile yePVC, ukufakwa, kunye neeprofayili.

3. Iiimpawuzahlukile

Ngokombono weempawu, i-PVC ethambileyo inemigca emihle yokwelula, inokwandiswa, kwaye inokumelana kakuhle nokushisa okuphezulu kunye nokuphantsi. Ke ngoko, isenokusetyenziswa ukwenza amalaphu etafile acacileyo. Ubushushu bokusetyenziswa kwe-PVC enzima ngokubanzi ayidluli kwiidigri ezingama-40, kwaye ukuba iqondo lobushushu liphezulu kakhulu, iimveliso ze-PVC ezinzima zinokonakala.

4. Iiipropatizahlukile

Ubuninzi bePVC ethambileyo yi-1.16-1.35g/cm ³, Izinga lokufunxa kwamanzi yi-0.15 ~ 0.75%, iqondo lokutshintsha kweglasi yi-75 ~ 105 ℃, kunye nesantya sokubunjwa kwe-10 ~ 50 × 10- ³cm/cm. I-PVC enzima ngokuqhelekileyo inobubanzi obuyi-40-100mm, iindonga zangaphakathi ezigudileyo ezinokumelana okuphantsi, akukho kunyuka, okungeyona ityhefu, ukungcola-free, kunye neepropati ezixhathisayo ku-corrosion. Iqondo lokushisa lokusetyenziswa alikho ngaphezu kwama-40 degrees, ngoko ke ngumbhobho wamanzi abandayo. Ukumelana kakuhle nokwaluphala kunye nokunqanda umlilo.
