Ọkpụkpọ PVC (PVC-U ọkpọkọ) ọkpọkọ PVC siri ike, bụ nke PVC resin na stabilizer, mmanu na ndị ọzọ na-ekpo ọkụ na-ekpo ọkụ extrusion ịkpụzi, bụ nke mbụ mepụtara na etinyere ọkpọkọ rọba.PVC-U ọkpọkọ nwere nguzogide corrosion siri ike, njikọ dị mfe, ọnụ ala dị ala na udidi siri ike.Otú ọ dị, n'ihi ntapu nke PVC-U monomer na mgbakwunye, ọ bụ naanị adabara maka mmiri ọkọnọ usoro ebe ibuga okpomọkụ adịghị gafere 45 ℃.A na-eji ọkpọkọ rọba maka igbapu, mmiri mkpofu, kemịkalụ, ikpo ọkụ na mmiri jụrụ oyi, nri, mmiri mmiri dị ọcha, apịtị, gas, ikuku abịakọrọ na ngwa sistemu agụụ.
Ọ nwere ezigbo nkwụsịtụ na ike mkpakọ: mana mgbanwe ya adịghị mma dị ka ọkpọkọ plastik ndị ọzọ.
Nguzogide mmiri dị ala: mgbidi PVC-U dị mma nke ukwuu, na iguzogide mmiri dị ntakịrị.Ọnụ ọgụgụ ya siri ike bụ naanị 0.009, na ikike mbufe mmiri ya dị 20% dị elu karịa nke ọkpọkọ nkedo nke otu dayameta, yana 40% dị elu karịa nke ọkpọkọ kọnti.
Ezigbo nguzogide corrosion na nguzogide ọgwụ: PVC-U ọkpọkọ nwere nguzogide acid dị mma, nguzogide alkali na nguzogide corrosion.Mmiri na ala pH adịghị emetụta ya, ọ dịghịkwa mkpa ọgwụgwọ mgbochi corrosion ọ bụla mgbe etinyere ọkpọkọ.
Na ezigbo njigide mmiri: ntinye nke PVC-U pipe nwere ezigbo mmiri siri ike, ma ọ na-ejikọta ya na nrapado ma ọ bụ mgbanaka roba.
Ihe akaebe na-egosi: PVC-U tube abụghị isi iyi nke nri na ya mere ọ dịghị enwe ike ịwakpo òké.Dika nyocha nke National Health Foundation mere na Michigan, oke anaghị ata ọkpọkọ PVC-U.
Nnwale arụmọrụ: oge ọgwụgwọ, ọnụego mbelata, ike nkewa, ike iwepụ ihe onwunwe tensile, nkwụsi ike okpomọkụ, oge ọdabara, oge nchekwa, ntọhapụ nke ihe ndị na-emerụ ahụ.
Usoro nke mmepụta
Ngwakọta akụrụngwa + nkwadebe inyeaka → ịgwakọta → ibufe na nri → inye nri mmanye → ụdị cone-ụdị ejima-screw extruder → extrusion ebu → size sleeve → fesa oghere ntọala igbe → teta mmiri jụrụ oyi → igwe obibi ink → crawler traktọ → igwe ebuli mma → tube stacking rack → Emechara nnwale ngwaahịa na nkwakọ ngwaahịa.
Enwere ike kewaa PVC n'ime PVC dị nro na PVC siri ike.
Ihe ndekọ PVC siri ike maka ihe dịka 2/3 nke ahịa, yana PVC dị nro maka 1/3.
A na-ejikarị PVC dị nro mee ihe maka ala, uko ụlọ na elu akpụkpọ anụ, ma n'ihi na PVC dị nro nwere plasticizer (nke a bụkwa ihe dị iche n'etiti PVC dị nro na PVC siri ike), arụ ọrụ anụ ahụ adịghị mma (dị ka ọkpọkọ mmiri kwesịrị ibu ụfọdụ nrụgide mmiri.
