Imibhobho yePolyvinyl chloride (PVC) ibe yinto ekhoyo kuyo yonke indawo kwiziseko ezingundoqo zale mihla, ulwakhiwo, kunye nokusetyenziswa kwemibhobho yamanzi. Ukuhlala kwabo, ukufikeleleka, kunye nokuguquguquka kwezinto kubenze ukuba bakhethe ukhetho olukhethiweyo kwiiprojekthi ezininzi. Kodwa ngaba wakha wazibuza ukuba le mibhobho yenziwa njani?
Kwesi sikhokelo sibanzi, siza kugocagoca kwinkqubo entsonkothileyo yokwenziwa kombhobho wePVC, sikuthatha kwimathiriyeli ekrwada ukuya kwimveliso egqityiweyo.
Inyathelo 1: Ulungiselelo lweMathiriyeli ekrwada
Uhambo lwemveliso yombhobho wePVC luqala ngokuthengwa kwezinto ezisetyenziswayo. Isithako esiphambili yi-PVC resin, umgubo omhlophe ophuma kwi-ethylene kunye ne-chlorine. Izongezo, ezifana nezinzisi, izihluzi, kunye nezinto zokuthambisa, nazo zifakwe ukunyusa iimpawu zepayipi kunye neempawu zokucubungula.
Inyathelo 2: Hlanganisa kwaye udibanise
Izinto eziphathekayo ezilinganiswe ngononophelo zithunyelwa kwi-high-speed mixer, apho zixutywe ngokucokisekileyo zibe ngumxube we-homogeneous. Le nkqubo, eyaziwa ngokuba yi-compounding, iqinisekisa ukuba izithako zihanjiswa ngokulinganayo, ukudala izinto ezifanayo kumanyathelo alandelayo.
Inyathelo 3: Extrusion
Umxube odityanisiweyo wePVC uye wondliwa kwi-extruder, umatshini oguqula izinto zibe yiprofayili eqhubekayo. I-extruder iqukethe i-barrel eshushu kunye ne-screw mechanism enyanzela i-PVC etyhidiweyo kwi-die. Ubume bokufa bumisela iphrofayili yombhobho, njengomgangatho, ishedyuli ye-40, okanye ishedyuli ye-80.
Inyathelo 4: Ukupholisa kunye nokuBumba
Njengoko umbhobho wePVC okhutshiweyo uphuma kwi-die, udlula kwindawo yokupholisa, apho amanzi okanye umoya usetyenziselwa ukuqinisa ngokukhawuleza izinto. Le nkqubo yokupholisa inqanda umbhobho ukuba ungaguquki kwaye iqinisekisa ukumila kwayo kunye nemilinganiselo efanelekileyo.
Inyathelo lesi-5: Ukusika kunye nokugqiba
Xa sele upholile, umbhobho wePVC unqunyulwa ubude obufunwayo usebenzisa iisarha okanye ezinye iimatshini zokusika. Iziphelo zemibhobho ke zibethelwa okanye zihlanjululwe ukuze ziququzelele ukujoyina kunye nokufakwa.
Inyathelo lesi-6: Ulawulo loMgangatho
Kuyo yonke inkqubo yokuvelisa, amanyathelo angqongqo okulawula umgangatho aphunyezwa ukuqinisekisa ukuba imibhobho ye-PVC ihlangabezana neenkcukacha ezifunekayo. Oku kubandakanya ukuhlolwa kobukhulu, uvavanyo loxinzelelo, kunye nokuhlolwa okubonakalayo kwiziphene.
Inyathelo 7: Ukugcinwa kweMveliso kunye noKwabiwa
Imibhobho ye-PVC egqityiweyo igcinwe ngokucophelela kwaye iphathwe ukukhusela umonakalo kunye nokugcina ingqibelelo yabo. Emva koko zipakishwa kwaye zithunyelwe kubathengisi kunye nabathengisi ukuze basetyenziswe ekugqibeleni kwizicelo ezahlukeneyo.
Indima yePVC yeMibhobho yoMveliso weMibhobho
Imigca yemveliso yemibhobho yePVC idlala indima ebalulekileyo ekuhlengahlengiseni nasekuzenzeleni inkqubo yokuvelisa. Ezi nkqubo zikhethekileyo zibandakanya bonke oomatshini kunye nezixhobo eziyimfuneko, ukusuka ekutyiseni izinto ezikrwada ukuya ekupakishweni kwemveliso yokugqibela, ukuqinisekisa imveliso esebenzayo nengaguqukiyo yemibhobho yePVC ekumgangatho ophezulu.
Imigca yemveliso yemibhobho yanamhlanje ye-PVC ixhotyiswe ngeenkqubo zolawulo eziphucukileyo ezibeka iliso kwaye zilawule iiparamitha ezahlukeneyo, ezifana nobushushu, uxinzelelo, kunye nesantya sokukhupha. Oku kuzenzekelayo kuqinisekisa ulawulo oluchanekileyo phezu kwenkqubo yokuvelisa, okukhokelela kumgangatho wemveliso ongaguqukiyo kunye nokunciphisa inkunkuma.
Ukuqukumbela
Ukuveliswa kombhobho wePVC yinkqubo entsonkothileyo neneenkalo ezininzi ezibandakanya ukukhetha ngononophelo kwezinto ezikrwada, ukuxubana okuchanekileyo, ukukhutshelwa ngaphandle okulawulwayo, ukupholisa, ukusika, nokulawula umgangatho. Isiphumo semibhobho yePVC ngamacandelo ayimfuneko kwiziseko ezingundoqo zala maxesha, ulwakhiwo, kunye neeprojekthi zemibhobho yamanzi, ebonelela ngokuqina, ukufikeleleka, kunye nokuguquguquka koluhlu olubanzi lwezicelo.
Ukuqonda inkqubo yokuvelisa umbhobho wePVC akuboneleli nje kuphela ekuvekweni kwezi nxalenye zibalulekileyo kodwa kukwaqaqambisa nokubaluleka kolawulo lomgangatho kunye nokuqhubela phambili kwezobuchwepheshe ekuqinisekiseni umgangatho wemveliso ongaguqukiyo kunye nemveliso esebenzayo.
