Ngenkxaso yabathengi abaninzi abasebenzisana ixesha elide, izisombululo zethu zamkelekile kwihlabathi liphela.

Imibhobho ye-PPR

Xa kuthelekiswa nemibhobho yesinyithi, imibhobho ye-PPR ineengenelo zokufakelwa okulula, ubushushu obungcono, kunye nokumelana nokugqwala. Yinto yokubonelela ngamanzi enempilo kwaye inobuhlobo nokusingqongileyo kwaye ikwayimveliso ephambili yokubonelela ngamanzi kwimarike. Imibhobho ye-PPR ifumaneka kakhulu ngemibala elandelayo, emhlophe, engwevu, eluhlaza kunye nemibala ye-curry, isizathu sokuba kubekho lo mahluko ubangelwa ikakhulu yimibala eyahlukeneyo ye-masterbatches eyongeziweyo.

Ukongeza kwiimpawu zemibhobho yeplastiki ngokubanzi ezifana nobunzima obulula, ukumelana nokugqwala, ukungakhuli, kunye nobomi benkonzo ende, imibhobho ye-PP-R ikwanazo ezi mpawu zilandelayo ziphambili:

1 Ayinabungozi kwaye ayicocekanga.
Iimolekyuli zezinto eziluhlaza ze-PP-R zizinto zekhabhoni ne-hydrogen kuphela, kwaye azikho izinto ezinobungozi nezinobuthi. Zicocekile kwaye zithembekile. Azisebenzi kuphela kwimibhobho yamanzi abandayo nashushu, kodwa nakwiinkqubo zamanzi okusela acocekileyo.

2 Ukugcinwa kobushushu nokonga amandla.
Ukuqhuba kobushushu bombhobho we-PP-R yi-0.21w/mk, eyi-1/200 kuphela yombhobho wentsimbi.

3 Ukumelana nobushushu okungcono.
Indawo yokuthambisa yeVicat yombhobho wePP-R yi-131.5℃. Ubushushu obuphezulu bokusebenza bungafikelela kwi-95℃, nto leyo enokuhlangabezana neemfuno zenkqubo yamanzi ashushu kwikhowudi yokuhambisa amanzi kunye nokukhupha amanzi kwisakhiwo.

4Ubomi benkonzo ende.
Phantsi kweemeko zobushushu obusebenzayo obuyi-70℃ kunye noxinzelelo lokusebenza (PN) lwe-1.0MPa, ubomi benkonzo yombhobho we-PP-R bunokufikelela kwiminyaka engaphezu kwama-50 (ukuba izinto zombhobho kufuneka zibe yi-S3.2 kunye ne-S2.5 series okanye ngaphezulu); phantsi kobushushu obuqhelekileyo (20℃) Ubomi benkonzo bunokufikelela kwiminyaka engaphezu kwe-100.

5 Ukufakela okulula kunye noqhagamshelo oluthembekileyo.
I-PP-R isebenza kakuhle ekudibaniseni. Iipayipi kunye nezixhobo zinokudityaniswa ngokunyibilika okushushu kunye nokudibanisa nge-electrofusion. Ukufakelwa kulula kwaye amalungu athembekile. Amandla elungu angaphezulu kwamandla elungu ngokwalo.

Izinto ezi-6 zingaphinda zisetyenziswe.
Inkunkuma ye-PP-R iyacocwa, iqhekezwe, ize isetyenziswe kwakhona ukuze isetyenziswe ekuveliseni imibhobho kunye nezixhobo. Ubungakanani bezinto ezisetyenzisiweyo abudluli kwi-10% yesixa siphela kwaye abuchaphazeli umgangatho wemveliso.

ufakelo

Izixhobo eziqhutywa kakuhle, iqela lokuthengisa elinobuchule, kunye neenkonzo ezingcono emva kokuthengisa; Sikwangusapho olukhulu oludibeneyo, wonke umntu unamathela kwixabiso lenkampani "umanyano, ukuzinikela, ukunyamezelana" komgangatho ogqwesileyo Umenzi we-Ifan imibala eluhlaza 45 ingqiniba 20mm-110mm zonke iintlobo zezixhobo ze-ppr amagama ukulungiswa kwe-ppr okukhawulezayo, Sidlala indima ephambili ekuboneleleni abathengi ngezinto ezisemgangathweni ophezulu Umboneleli olungileyo kakhulu kunye noluhlu lwamaxabiso olukhuphisanayo.
Umgangatho ogqwesileyo, Emva kweminyaka yophuhliso, ngoku sakhe ubuchule obuqinileyo ekuphuhlisweni kwemveliso entsha kunye nenkqubo yokulawula umgangatho ongqongqo ukuqinisekisa umgangatho ogqwesileyo kunye nenkonzo. Ngenkxaso yabathengi abaninzi abasebenzisana ixesha elide, izisombululo zethu zamkelekile kwihlabathi liphela.
