Umahluko phakathi kwePVC ethambileyo nePVC eqinileyo

I-PVC inokwahlulwa ibe zizinto ezimbini: i-PVC eqinileyo kunye ne-PVC ethambileyo. Igama lesayensi le-PVC yi-polyvinyl chloride, eyona nto iphambili kwiplastiki kwaye isetyenziswa kakhulu ekwenzeni iimveliso zeplastiki. Ixabiso liphantsi kwaye isetyenziswa kakhulu. I-PVC eqinileyo ithatha malunga nesibini kwisithathu semarike, ngelixa i-PVC ethambileyo ithatha isinye kwisithathu. Ngoko ke, yintoni umahluko phakathi kwe-PVC ethambileyo kunye ne-PVC eqinileyo?

1. Amanqanaba ahlukeneyo okuthamba kunye nobunzima

Umahluko omkhulu usekwe kubulukhuni babo obahlukeneyo. I-PVC eqinileyo ayinazo izithambisi, inokuguquguquka okuhle, kulula ukuyila, kwaye ayiqhekeki lula, ayinatyhefu kwaye ayinangcoliseko, igcinwa ixesha elide, kwaye inexabiso elihle lophuhliso kunye nokusetyenziswa. Kwelinye icala, i-PVC ethambileyo inezithambisi ezithambileyo, kodwa ithambekele ekubeni buthathaka kwaye ibe nzima ukuyigcina, ngoko ke ukusetyenziswa kwayo kulinganiselwe.

1. Iuluhlu lwesicelozahlukile

Ngenxa yokuguquguquka kwayo okuhle, i-PVC ethambileyo isetyenziswa ngokubanzi kumphezulu weetafuleni, umgangatho, isilingi, kunye nolusu; i-polyvinyl chloride eqinileyo isetyenziswa kakhulu kwimibhobho ye-PVC eqinileyo, izixhobo, kunye neeprofayili.

3. Iiimpawuzahlukile

Ngokwembono yeempawu, i-PVC ethambileyo inemigca emihle yokuzolula, inokwandiswa, kwaye inokumelana kakuhle nobushushu obuphezulu nobuphantsi. Ke ngoko, ingasetyenziselwa ukwenza amalaphu etafile acacileyo. Ubushushu bokusetyenziswa kwe-PVC eqinileyo ngokubanzi abudluli kwiidigri ezingama-40, kwaye ukuba ubushushu buphezulu kakhulu, iimveliso ze-PVC eqinileyo zinokonakala.

4. Iiipropatizahlukile

Uxinano lwe-PVC ethambileyo yi-1.16-1.35g/cm³, Izinga lokufunxwa kwamanzi yi-0.15~0.75%, ubushushu bokutshintsha kweglasi yi-75~105 ℃, kwaye izinga lokuncipha kokubumba yi-10~50 × 10-³cm/cm. I-PVC eqinileyo idla ngokuba nobubanzi obuyi-40-100mm, iindonga zangaphakathi ezigudileyo ezinokumelana okuphantsi, azinasikali, azinatyhefu, azingcolisi, kwaye azinamhlwa. Ubushushu bokusetyenziswa abudluli kuma-40 degrees, ngoko ke ngumbhobho wamanzi abandayo. Ukumelana nokuguga kakuhle kwaye kuyathintela ilangatye.
