Uhlalutyo lweNkqubo yoKuqulunqa iFabric yePVC

Ilaphu lePVC elilula, elastiki kakhulu kwaye lihlala ixesha elide, lisetyenziswa kakhulu kwiimveliso zangaphandle, iintente, amalaphu entengiso, kunye nezixhobo zokhuselo lwezonyango. Inkqubo yokwenziwa kwayo ichaphazela ngokuthe ngqo iipropathi ezibonakalayo zemveliso kunye nobomi benkonzo, oko kukwenza ukuba kube yimfuneko ukulawula ukuhamba kwenkqubo engundoqo.

Inkqubo yokwenziwa kwelaphu lePVC olululayo linamanyathelo amane angundoqo: ukuxuba imathiriyeli ekrwada, i-extrusion calendering, ukolula kunye nokuqhelaniswa, kunye-nokusetyenzwa. Okokuqala, i-polyvinyl chloride (PVC) i-resin ixutywa kunye nezongezelelo ezifana ne-plasticizers, i-stabilizers, kunye ne-lubricant ngokomlinganiselo ofanelekileyo kwaye isasazwe ngokulinganayo kwi-speed blender ukwenza intlama ene-viscosity ethile. Ukhetho lwezongezo kweli nqanaba luchaphazela ngokuthe ngqo ukuguquguquka kwezinto, ukumelana nemozulu, kunye nokuchasana kwe-UV.

Umxube ke ungena kwi-extruder, apho inyibilika kwiqondo lokushisa eliphezulu (malunga ne-160{1}}180 degree) kwaye ikhutshwe nge-T-die ibe kwiphepha. Iphepha ke lifakwa kwi-calender kunye ne-roller ukulawula ubukhulu kunye nokugudiswa komphezulu. Ukushisa kwe-calendering kufuneka kulawulwe ngokuchanekileyo ukuphepha ukubola kwezinto ngenxa yokufudumala okanye uxinzelelo lwangaphakathi olubangelwa ukupholisa ngaphantsi.

Ukolula kunye nokuqhelaniswa yinkqubo ephambili enikezela ngelaphu lePVC elinokwelula okuphezulu. Ishiti lifudunyezwa ngaphambili (ngokwesiqhelo ngama-80-i-120 idigri) phambi kokuba lisolulwe nge-uniaxially okanye nge-biaxially kumatshini wokuzolula ubude obude okanye obunqamlezayo. Umlinganiselo wokwelula ngokuqhelekileyo ngamaxesha angama-2-5, ukulungelelanisa amakhonkco e-molecular kwicala lamandla, ukuphucula kakhulu ukunyusa kunye nokuqina kwezinto. Ezinye iimveliso ezikumgangatho ophezulu zisebenzisa itekhnoloji yokwelula ngokulandelelanayo ukongeza ngakumbi ibhalansi yomatshini.

Ekugqibeleni, ilaphu eloluliweyo libeka ubushushu kunye nokupholisa. Ukushisa ubushushu kubandakanya ixesha elifutshane lobushushu obuphezulu (malunga ne-100-i-130 degree) ukuzinzisa isakhiwo se-molecular kunye nokuphelisa uxinzelelo olushiyekileyo. Ukupholisa kwenziwa ngomoya okanye ngamanzi ukuqinisekisa uzinzo lwe-dimensional. Ezinye iimveliso zikwafuna unyango olungaphezulu, olunje nge-UV-resistant-retardants okanye i-flame retardants, ukuphucula ukusebenza.

Inkqubo yokubumba i-PVC yolula ilaphu ifuna ulawulo olungqongqo lobushushu, isantya, kunye noxinzelelo. Ukuphambuka kulo naliphi na inyathelo kunokubangela ukusebenza kwezinto ezikumgangatho ophantsi. Inkqubela phambili yezobuchwephesha, njengokungeniswa kokubekwa kweliso kwi-intanethi kunye nolawulo oluzenzekelayo, kuqhuba iinkqubo zale mihla ezibhekiselele kwimpumelelo enkulu kunye nokulungelelana kokusingqongileyo, ukubonelela ngezisombululo eziphezulu zezinto zokusebenza kwizicelo ezisezantsi.
