Hobaneng re lokela ho khetha valve ea PPH, ho kenya liphaephe kapa phala

Valve ea PPH ke mofuta oa valve o entsoeng ka thepa ea polypropylene (PP), e nang le litšobotsi tse bobebe, tlhokomelo e bonolo, phetoho e ntle joalo-joalo, kahoo ho na le lisebelisoa tse ngata tsa tlhahiso le bophelo. Tse latelang ke tse ling tsa lisebelisoa tse tloaelehileng:

Indasteri ea lik'hemik'hale:

Ka indasteri ea lik'hemik'hale, li-valve tsa PPH li sebelisoa haholo ho laola liphaephe tsa mecha ea litaba e senyang, e kang acid, alkali, letsoai joalo-joalo. Ka lebaka la ts'ebetso ea eona e ntle ea ho thibela kutu le thepa e matla e thibelang botsofali, li-valve tsa PPH li ka sebetsa ka mokhoa o tsitsitseng ka nako e telele, e leng se netefatsang polokeho le botsitso ba tlhahiso ea lik'hemik'hale.

Indasteri ea ho hloekisa metsi:

Li-valve tsa PPH li boetse li sebelisoa haholo tšimong ea ho hloekisa metsi le ho hloekisa likhoerekhoere. Ka lebaka la ts'ebetso ea eona e ntle ea bohloeki, ha e na lintho tse chefo, li-valve tsa PPH ts'ebetsong ea ho hloekisa metsi li ke ke tsa hlahisa tšilafalo ea bobeli ea boleng ba metsi, kahoo indastering ea phekolo ea metsi e ratoa haholo.

Indasteri ea lijo:

Indastering ea lijo, li-valve tsa PPH li sebelisoa haholo mekhoeng ea ho lokisa le ho paka ka lebaka la litšobotsi tsa tsona tse se nang chefo, tse se nang monko le tse hananang le kutu. Ka mohlala, tlhahisong ea seno, li-valve tsa PPH li ka sebelisoa ho laola ho phalla le tataiso ea ho phalla ha lino; ka har'a liphutheloana tsa lijo, li-valve tsa PPH li ka sebelisoa ho laola lits'ebetso tsa vacuum le sistimi ea moea.

Indasteri ea meriana:

Lefapheng la meriana, li-valve tsa PPH li sebelisoa haholo ho hlahisa, ho boloka le ho tsamaisa meriana ka lebaka la bohloeki ba tsona bo phahameng le ho hanyetsa ho hotle ha kutu. Ka mohlala, li-valve tsa PPH li ka sebelisoa ho laola tataiso ea phallo le tekanyo ea phallo ea meriana nakong ea ho tlatsa; polokelong ea meriana, li-valve tsa PPH li ka sebelisoa ho laola mongobo le mocheso oa ntlo ea polokelo.

Mmarakeng, ho na le UPVC, CPVC, PPH, PVDF, valve ea FRPP, le tsamaiso ea lipeipi. Lebaka le latelang le reng Ke hobane'ng ha re lokela ho khetha valve ea PPH, ho kenya lipeipi kapa peipi?

Sebopeho sa thepa ea PPH ke efe?

Polypropylene Homopolymer (PP-H) ke mofuta o mong oa PP. E na le mocheso o betere le khanyetso ea creep ho feta PPR, 'me e na le tšusumetso e matla ea mocheso.

Hajoale liphaephe le lisebelisoa tsa PPH li ts'epahala haholo litsing tsa lipeipi tsa metsi le phepelo ea metsi, ka lebaka la likarolo tsa tsona tsa lik'hemik'hale le welding ea fusion, e netefatsang hore lipeipi li na le sistimi e tiileng ea tiiso. E amohetsoe ke Mokhatlo oa Bophelo o nang le litšobotsi tse kang Eco-friendly le mocheso o phahameng oa ho hanyetsa, liphaephe le lisebelisoa tsa PPH / PPR li nkiloe e le e 'ngoe ea tharollo e molemo ka ho fetisisa bakeng sa tsamaiso ea liphaephe.

Mocheso o phahameng oa liphaephe tsa PPH ke 110 ℃, 'me hangata li sebelisoa ka tlase ho 90 ℃. Li sebelisoa bakeng sa phetisetso ea metsi a pholileng, phetisetso ea lintho tse senyang, likotopo tsa mosi, litsamaiso tsa electrolyze, le lits'ebetso tse ling tsa liphaephe tse nang le metsi a acid.
