Ukukhetha i-hose impahla efanelekileyo ibalulekile kwizicelo zokutshintshwa kweekhemikhali, kunyeUmbhobho wePVClukhetho oluqhelekileyo olunikezela ngeenzuzo ezizodwa kunye nokungalunganga ngaphezu kwezinye izinto. Kwesi sihloko, siya kuthelekisaUmbhobho wePVCkunye nezinye izinto zokunceda abasebenzi beshishini bakhethe ngcono imathiriyeli yombhobho efanelekileyo kwiimfuno zabo.
Enye yeenzuzo zeUmbhobho wePVCukudluliselwa kweekhemikhali kukuhambelana kwayo kakuhle kweekhemikhali. I-PVC inokumelana kakuhle neeasidi ezininzi, iziseko kunye neekhemikhali, kodwa isenokungalungeli kangako izinyibilikisi ezithile kunye neehydrocarbons. Ngokwahlukileyo, i-hose yerabha inoluhlu olubanzi lokuxhathisa imichiza kwii-solvents ezininzi kunye nee-hydrocarbons.
Ukongezelela, ukuguquguquka kwe-hose yinto ebalulekileyo yokuqwalasela.pvc umbhobhoibhetyebhetye ngokubanzi, kulula ukuyiphatha kwaye ilungele usetyenziso olwahlukeneyo. Imibhobho yerabha nayo iyaguquguquka kwaye inokuhlala iguquguquka kumaqondo obushushu aphantsi.
Ekugqibeleni, iindleko zikwayinto ebalulekileyo ekunqumeni ukhetho lwe-hose.pvc ithumbu mnas iqhele ukuba lolona khetho lungabizi kakhulu, ngelixa ithumbu lerabha kunye nombhobho we-PTFE zidla ngokubiza kakhulu. Nangona kunjalo, kwiimfuno ezikhethekileyo zokudluliselwa kweekhemikhali, iindleko zisenokungabi yeyona nto ibalulekileyo eqwalaselwayo.
Isishwankathelo, ukukhetha izinto ezifanelekileyo ze-hose kufuna ukudibanisa ukuhambelana kweekhemikhali, ukumelana nokushisa, ukuguquguquka kunye neendleko. Kwizicelo zokudluliselwa kweekhemikhali ngokubanzi,Umbhobho wePVCisenokuba lukhetho olufanelekileyo, kodwa kwiimfuno ezibango ngakumbi zokudluliselwa kweekhemikhali, irabha okanye ithumbu le-PTFE inokufaneleka ngakumbi. Ke ngoko, iingcali zeshishini kufuneka zikhethe ezona zixhobo zifanelekileyo ze-hose kwiimfuno zabo ezithile zokuqinisekisa ukuba ukuhanjiswa kweekhemikhali kwenziwa ngokukhuselekileyo nangokufanelekileyo.
