Kuyini ukufakwa kwe-ppr?

izinto zokufakelwa, ezenziwe nge-Polypropylene Random Copolymer, zisebenza njengezingxenye ezibalulekile ezinhlelweni zamapayipi. Baxhuma amapayipi ukuze kuqinisekiswe ukuthuthwa kwamanzi okusebenzayo. Impahla yabo eqinile imelana nokuguga, okuyenza ibe ilungele amapayipi esimanje. Ngokunikeza ukuqina nokuthembeka, ukufakwa kwe-PPR sekuphenduke isisekelo sezinhlelo zokusebenza zokuhlala nezimboni.

Okuthathwayo Okubalulekile

• Ukufakwa kwe-PPR kunamandla futhi akugqwali noma akuphuki kalula. Baphatha kahle ukushintsha kwezinga lokushisa, okwenza kube kuhle ekufakeni amapayipi.
• Lokhu kufakwa kungasebenza kuze kube yiminyaka engama-50. Lokhu kwehlisa izindleko zokulungisa futhi kubenze bathembeke ezindlini nasezimbonini.
• Ukufakwa kwe-PPR kulula ukukuhlanganisa ne-heat fusion welding. Le ndlela yenza amajoyinti aqinile, angavuzi futhi yonga isikhathi nemali.

Izici Ezibalulekile Zokufakwayo kwe-PPR

Ukubunjwa Kwezinto Ezibalulekile

Ukufakwa kwe-PPR kwenziwa ngenhlanganisela ekhethekile ye-polypropylene ne-ethylene copolymers. Lokhu kwakheka okuyingqayizivele kuqinisekisa ukuqina nokuthembeka okukhethekile. Abakhiqizi basebenzisa izinto zokusetshenziswa zebanga eliphezulu ukuze benze lezi zinto zokufakwayo, okuthuthukisa ikhono labo lokubhekana nezidingo zezinhlelo zamapayipi zamapayipi zanamuhla.

Isakhiwo samangqamuzana e-polypropylene random copolymer (PPR) sidlala indima ebalulekile ekusebenzeni kwayo. Ukuhlelwa kwayo kwe-propylene kanye ne-ethylene monomers, kuhlanganiswe nokuba khona kwamaqembu e-methyl, kunikeza ukuzinza ngokumelene nama-acids amancane nama-alkali. Lokhu kuzinza kuqinisekisa ukuthi ukufakwa kwe-PPR kugcina ubuqotho bakho ngisho nangemva kokuchayeka isikhathi eside ezinto ezonakalisayo.

Izici eziyinhloko zokwakheka kwezinto zifaka:

• Inhlanganisela ye-polypropylene ne-ethylene copolymers.
• Izinto zokusetshenziswa ezisezingeni eliphezulu zokuqina okuthuthukisiwe.
• Ukumelana ne-oxidation kanye nokuwohloka kwamakhemikhali.

Izinga Lokushisa Nokumelana Nokucindezela

Ukufakwa kwe-PPR kubonisa ukumelana okuphawulekayo nokushintshashintsha kwezinga lokushisa nezimo zokucindezela okuphezulu. Zenzelwe ukusebenza ngempumelelo ezindaweni ezinamazinga okushisa asukela ku -20°C kuya ku-95°C. Lolu hlu olubanzi lokushisa lubenza bafanelekele izinhlelo zokusebenza ezihlukahlukene, okuhlanganisa amapayipi okuhlala kanye nokuthutha uketshezi lwezimboni.

Amandla okufakwa kwe-PPR okubekezelela ukujikeleza okuphindaphindiwe kwezinga lokushisa kuvimbela ukuwohloka kwezinto ezibonakalayo kanye nokwehluleka okungaba khona. Lesi sakhiwo sibaluleke kakhulu kumasistimu athola ukwanda nokuncipha njalo ngenxa yokushintsha kwezinga lokushisa. Ngokugcina ubuqotho bazo besakhiwo, ukufakwa kwe-PPR kunciphisa ubungozi bokuvuza nobungozi, ikakhulukazi ezinhlelweni ezibucayi.

Izinzuzo zokumelana nezinga lokushisa nokucindezela zihlanganisa:

• Ukusebenza emazingeni okushisa aphezulu (-20°C kuya ku-95°C).
• Ukuvinjelwa kokusebenza buthaka ngenxa yezinga lokushisa elijikelezayo.
• Ukuphepha okuthuthukisiwe kumasistimu anengcindezi ephezulu.

Ukugqwala kanye Nokumelana Namakhemikhali

Esinye sezici ezivelele zokufakwa kwe-PPR ukumelana kwazo nokugqwala nokulimala kwamakhemikhali. Lesi sici siqinisekisa ukusebenza kwesikhathi eside ezindaweni lapho ukuchayeka kuma-asidi, ama-alkali, nezinye izinto ezonakalisayo kuvame.

Ithebula elilandelayo ligqamisa ukumelana kwamakhemikhali kokufakwa kwe-PPR:

Lokhu kumelana okukhethekile kwenza ukufakwa kwe-PPR kube ukukhetha okuthembekile kuzo zombili izinhlelo zokusebenza zokuhlala nezimboni. Ikhono labo lokumelana namakhemikhali anokhahlo liqinisekisa isikhathi eside sokuphila kanye nokunciphisa izindleko zokunakekela.

Izinhlobo Ezijwayelekile Zokufakwa Kwe-PPR

Izindololwane kanye Tees

Ama-elbows nama-tee aphakathi kwe-PPR esetshenziswa kakhulu. Benza lula izinguquko endleleni yepayipi futhi bavumele amapayipi amaningi ukuthi axhume endaweni eyodwa. Izindololwane zivame ukuza ngama-engeli angu-45-degree kanye nama-degree angu-90, kuyilapho ama-tees anika amandla ukuxhumana okunezindlela ezintathu. Lokhu kufakwa kubalulekile kuzo zombili izinhlelo zokubeka amapayipi ezihlala nezimboni.

Inqubo yokukhiqiza izindololwane nezinsikazi igcizelela ukunemba nokuqina. Ikhwalithi ephezulu yePolypropylene Random Copolymer (PPR) iqinisekisa ukumelana nokuguquguquka kwezinga lokushisa nokucindezeleka kwemishini. Ukunemba kwe-Dimensional kubalulekile ukuvimbela ukuvuza nokuqinisekisa ukuhambisana namapayipi. Ukwengeza, lezi zifakelo zigcina ubuqotho besakhiwo kulo lonke izinga lokushisa elibanzi, okuzenza zifanelekele izinhlelo zamanzi ashisayo nabandayo.

Idizayini Amazinga Endololwane Nezintshakazana:
