Umbhobho wePVC (umbhobho wePVC-U) umbhobho we-PVC onzima, wenziwa nge-PVC ye-resin ene-stabilizer, i-lubricant kunye nezinye i-extrusion yokubumba eshushu, ngowona mbhobho wokuqala ophuhliswe kwaye wasetyenziswa.Umbhobho wePVC-U unoxhathiso oluluqilima lwe-corrosion, i-bonding elula, ixabiso eliphantsi kunye nobulukhuni obunzima.Nangona kunjalo, ngenxa yokuvuza kwe-PVC-U monomer kunye nezongezo, ilungele kuphela inkqubo yonikezelo lwamanzi apho ubushushu bokuhambisa bungagqithi kwi-45 ℃.Imibhobho yePlastiki isetyenziselwa ukuhambisa amanzi, amanzi amdaka, iikhemikhali, ukufudumeza kunye nolwelo lokupholisa, ukutya, ulwelo olusulungekileyo, udaka, igesi, umoya ocinezelweyo kunye nenkqubo yokufunxa.

Inokuqina okuhle kunye namandla oxinzelelo: kodwa ukuguquguquka kwayo akulunganga njengeminye imibhobho yeplastiki.

Ukuxhathisa ulwelo oluphantsi: udonga lwePVC-U umbhobho lugudileyo kakhulu, kwaye ukuchasana nolwelo kuncinci kakhulu.I-coefficient ye-roughness yayo yi-0.009 kuphela, kwaye umthamo wayo wokuthutha amanzi ungaphezulu kwama-20% kunombhobho we-iron we-diameter efanayo, kunye ne-40% ephezulu kunombhobho wekhonkrithi.

Ukuxhathisa umhlwa okugqwesileyo kunye nokumelana neziyobisi: umbhobho we-PVC-U unokumelana ne-asidi ebalaseleyo, ukuxhathisa kwealkali kunye nokumelana nomhlwa.Ayichaphazeli umswakama kunye ne-pH yomhlaba, kwaye ayifuni naluphi na unyango oluchasene ne-corrosion xa kufakwe umbhobho.

Ngoxinzelelo oluhle lwamanzi: ukufakwa kombhobho we-PVC-U kunobunzima bamanzi obuhle, nokuba udibaniswe ne-adhesive okanye i-rubber ring.

Ubungqina bokuluma: Iityhubhu ze-PVC-U aziyiyo imithombo yezondlo kwaye ngoko ke ayinakuchaphazeleka kuhlaselo lweempuku.Ngokophononongo olwenziwa yiNational Health Foundation eMichigan, iimpuku azilumi umbhobho wePVC-U.

Uvavanyo lokusebenza: ixesha lokunyanga, izinga lokucutheka, amandla okuqhekeka, amandla okuhlutha impahla, ukuzinza kwe-thermal, ixesha elisebenzayo, ixesha lokugcina, ukukhutshwa kwezinto ezinobungozi.

Inkqubo yemveliso

Imathiriyeli ekrwada + ulungiselelo oluncedisayo → ukuxuba → ukuhambisa kunye nokutyisa → ukutyisa ngenkani → Udidi lwe-cone-screw extruder → ukungunda kwe-extrusion → umkhono wokulinganisa → ibhokisi yokuseta ivacuum → ukufunxwa itanki yamanzi okupholisa → umatshini wokushicilela we-inki → umatshini wokuphakamisa imela → umatshini wokuphakamisa imela → umbhobho wokupakisha → uvavanyo olugqityiweyo lwemveliso kunye nokupakishwa.

I-PVC inokohlulwa ibe yi-PVC ethambileyo kunye ne-PVC enzima.

I-akhawunti ye-PVC enzima malunga ne-2/3 yemarike, kunye ne-akhawunti ye-PVC ethambileyo ye-1/3.

I-PVC ethambileyo isetyenziswa ngokubanzi kumgangatho, isilingi kunye nomphezulu wesikhumba, kodwa ngenxa yokuba i-PVC ethambileyo iqulethe i-plasticizer (oku ikwangumahluko phakathi kwe-PVC ethambileyo kunye ne-PVC enzima), ukusebenza komzimba kumbi (njengoko imibhobho yamanzi ifuna ukuthwala uxinzelelo oluthile lwamanzi, I-PVC ethambileyo ayifanelekanga ukusetyenziswa), ngoko ke umda wokusetyenziswa kwayo ulinganiselwe.

I-PVC enzima ayinayo i-plasticizer, ngoko kulula ukuyifaka, iipropati ezintle zomzimba, ngoko inophuhliso olukhulu kunye nexabiso lesicelo.Kwinkqubo yokuvelisa izinto zePVC, izongezelelo ezininzi ziya kongezwa, njenge-stabilizer, plasticizer kunye nokunye.Ukuba zonke izongezo zokusingqongileyo zisetyenzisiwe, umbhobho wePVC awunayo ityhefu kunye neemveliso zokhuselo lokusingqongileyo ezingenancasa.
