Ithumbu lePVC elomeleziweyoyimveliso engenakwahlulwa ebomini bethu. Kukho iintlobo ezininzi of PVC imibhobho. Phakathi kwazo, iimveliso ezisebenzisa irabha yethu engumgubo ye-nitrile i-P8300 ibandakanya i-PVC yoxinzelelo oluphezulu lwemibhobho yomoya, i-hoses ye-oksijini yoxinzelelo oluphezulu, kunye nemibhobho yegesi yendalo yasekhaya / yamashishini. , imibhobho yerhasi enyibilikisiweyo, imibhobho yerhasi, imibhobho yokutshiza yezolimo enoxinzelelo oluphezulu yePVC, imibhobho yokuntywila enoxinzelelo oluphezulu, imibhobho yerhasi enombala ethambileyo, imibhobho yeoli ekwaziyo ukumelana nobushushu obuphezulu, kunye nemibhobho yomlilo, njl. njl., masiyilungiselele wonke umntu! Khumbula ukuthatha incwadi encinci kwaye uyibhale phantsi ~
Indlela yokubiza i-PVC yombhobho wokuqinisa, iimfuno zayo kufuneka ubuncinane zihlangabezane nezi mpawu zisisiseko: ukumelana noxinzelelo oluphezulu, ukumelana nokwaluphala, ukuxhathisa ukunxiba, ukuthamba kunye nokuqina, ukuxhathisa ukutsala, ukuxhathisa ukungcangcazela, ukumelana nokubanda, ukuxhathisa ukubola, ukuxhathisa kwe-asidi kunye ne-alkali, i-flame retardant , Imveliso ayithambilenga xa ishushu, ilula kwaye ihlala ixesha elide.
Nangona kunjalo, i-hoses eqinisiweyo ye-PVC eveliswa ngabavelisi abaninzi ayinakuhlangabezana nezi zakhiwo zisisiseko konke konke. Kunoko, kuya kubakho iingxaki ezahlukeneyo, ezifana ne-oven ayikwazi ukumelana nokushisa okuphezulu kunye nokuqhuma, uvavanyo lwe-oven's tensile alwanelanga, njl. Kakade ke, ngaphezu kwenkqubo yokuvelisa, ukulawula ubushushu, isantya se-Extrusion, njl., eyona nto ibaluleke kakhulu kukukhetha izinto eziphathekayo ezifanelekileyo. Eyona nto iphambili kwimveliso yeIthumbu lePVC elomeleziweyoyi polyvinyl chloride (PVC) resin. I-PVC ngokwayo ayinayo i-elastic kunye ne-flexible chain structure, ngoko ke ukumelana nobushushu obuphantsi bubi. Irabha ye-nitrile engumgubo i-NBR-P8300, njenge-elastomer, inomlinganiselo ophezulu wokuhambelana ne-PVC, kwaye yenza isakhiwo "sesiqithi" xa sihlanganiswe nePVC. Le nkqubo yokuxuba iyunifomu inokuphucula ngokufanelekileyo ukuguquguquka kwe-PVC, kunye nokuchasana kwayo okuphantsi kweqondo lokushisa kunokuphuculwa. Ukuphuculwa okusebenzayo, ngenxa yeengqungquthela zayo ezintle, ukusabalalisa okulungileyo kunye nokunyuka kwamanzi, iindawo ezithambileyo zeerubha kunye ne-elastomers zihanjiswa ngokufanayo kwizinto ezixubeneyo, ngaloo ndlela zinciphisa ukuchithwa kunye nokukrazula kweemveliso ezithambileyo ze-PVC.
Ukusetyenziswa kwerabha ye-nitrile engumgubo i-P8300 nayo iluncedo olukhulu ekuzinzeni kwe-plasticizer. Uninzi lweeplasticizers ezisetyenziswa kwi-PVC ethambileyo zizinto eziphantsi-molekyuli, kwaye iimveliso zivame ukutshiza ioli, iibhokisi zokutshiza, kunye nokutshiza ngexesha lokusetyenziswa. Kwaye ezinye iingxaki, ukongeza i-PNBR kunokunyusa ukomelela kwemveliso, ukunciphisa inani le-plasticizer esetyenzisiweyo, kwaye kwangaxeshanye kuncitshiswe isantya sokufuduka kweplasitiki ngenxa yomtsalane weplasitiki.
