Ukufakwa kwepayipi le-PPH
Ikhwalithi ephezulu yamapayipi we-PPH nokufakwa 1/2-8 - 3 Way & Equal Tee
Q. Iyini impahla ye-PPH
1. I-Homopolymer polypropylene material
Impahla ye-PPH iyi-homopolymer polypropylene material elungiswe ngu-β, enokumelana okuhle kakhulu namakhemikhali, ukumelana nezinga lokushisa eliphezulu, ukumelana nomthelela, kanye nokumelana kahle nokukhasa. I-PPH (i-Polypropylene Homeo) impahla, eyaziwa nangokuthi i-homo polypropylene, inokwakheka kwekristalu ye-beta efanayo futhi ethambile ngokuguqulwa kwe-β, okukhombisa ukumelana nokugqwala kwamakhemikhali, ukumelana nemihuzuko, ukumelana nezinga lokushisa okuphezulu, ukumelana nokugqwala, ukumelana nokuguga kanye nokufakwa kahle. Le nto ayisetshenziswa kakhulu ezimbonini ezifana nobunjiniyela bamakhemikhali, i-electronics, izimboni zemithi, nokwelashwa kwamanzi angcolile, kodwa futhi inezinhlelo zokusebenza eziningi emikhakheni eminingi ngenxa yezakhiwo zayo ezihlukile zomzimba namakhemikhali. Amapayipi wempahla we-PPH namapuleti enziwa aba okokusebenza okumelana nokugqwala futhi asetshenziswa kabanzi emikhakheni efana nobunjiniyela bamakhemikhali, i-metallurgy, ne-electronics, okufakazela ukusebenza kwawo okuhle kakhulu kanye nenani elibanzi lesicelo.
I-2.Izici eziyinhloko zezinto ze-PPH zihlanganisa:Ukumelana nezinga lokushisa elihle kakhulu: ukukwazi ukumelana nezimo zokushisa eziphezulu, ukugcina ukuqina kwezinto ezibonakalayo kanye nokuqina.
Ukumelana nokucindezela okuhle: kulungele ukusetshenziswa ezindaweni ezinomfutho ophezulu, okuqinisekisa ukusebenza okuphephile kwesistimu.
Ukumelana namakhemikhali: Inokumelana okuhle nezinto ezihlukahlukene zamakhemikhali, inweba impilo yesevisi yezinto ezibonakalayo.
Ukuphila okude: Ngenxa yokusebenza okuhle kakhulu okukhulunywe ngenhla, imikhiqizo eyenziwe ngezinto ze-PPH inempilo ende yesevisi.
Ukwengeza, impahla ye-PPH nayo inezinzuzo zokungabi nobuthi, ukungaboli, nokungalinganisi, okuyenza isebenze kakhulu futhi yonge kumaphrojekthi wokufakwa kwamapayipi. Sekukonke, impahla ye-PPH idlala indima ebalulekile emikhakheni yezimboni eziningi ngenxa yobuchwepheshe bayo bokuguqula obuhlukile kanye nokusebenza okuhle kakhulu, okuhlinzeka ngezixazululo ezinokwethenjelwa zezinhlelo zokusebenza ezahlukahlukene.
Q. Uyini umehluko phakathi kwe-PPH ne-PP
1. Kunomehluko omkhulu phakathi kwe-PPH ne-PP (i-polypropylene) mayelana nezakhiwo zezinto ezibonakalayo, izindawo zokufaka isicelo, amasu okucubungula, kanye nezindleko. Umehluko omkhulu phakathi kwabo umi kanje: 1
Izici zezinto ezibonakalayo kanye nenqubo yokukhiqiza
I-PPH (i-homopolymer polypropylene) yenziwa ngokushintsha isisindo samangqamuzana aphezulu, izinga lokuncibilika eliphansi lokugeleza kwe-homopolymer polypropylene ene-β, enokumelana okuhle kakhulu kwamakhemikhali, ukumelana nokushisa okuphezulu, nokumelana kahle nokukhasa, futhi ifanele izimo ezimbi kakhulu.
I-PP (i-polypropylene) ngokuvamile yenziwe nge-polypropylene random copolymer (RPP), enokumelana nokugqwala okuhle futhi ifanele ukuthuthwa kwamakhemikhali okuvamile.
2. Inkambu yohlelo lokusebenza
I-PPH ivame ukusetshenziswa ezinhlelweni zamanzi ashisayo, ezimbonini zamakhemikhali, nasezindaweni ezidinga izinga lokushisa eliphezulu nokumelana nokugqwala ngenxa yokushisa kwayo okuphezulu kakhulu nokumelana namakhemikhali.
I-PP isetshenziswa kakhulu ekuthuthweni koketshezi olune-asidi nolwe-alkali ezimbonini ezinjengamakhemikhali, i-electroplating, nokunyathelisa nokudaya ngenxa yokumelana kwayo nokugqwala okuhle kakhulu.
Ukucubungula ubuchwepheshe kanye nendlela yokuxhuma
Amapayipi e-PPH ngokuvamile axhunywe ngokushisela, ukuncibilika okushisayo, nezinye izindlela, ezinamandla okuxhumana aphezulu nokusebenza kokuvala, futhi afanelekela izindawo ezinokhahlo ezifana nokucindezela okuphezulu nokushisa okuphezulu.
Ngaphezu kokuxhumeka kwe-welding nokuncibilika okushisayo, amapayipi e-PP nawo angaxhunywa kusetshenziswa izindlela ezihlukahlukene ezifana nokuncibilika kukagesi, okuwenza aguquguquke futhi alula.
3. Izindleko
I-PPH ibiza kakhulu ngenxa yokumelana nokugqwala okuhle kakhulu nokumelana nezinga lokushisa eliphezulu, kodwa ithandwa kakhulu kwamanye amaphrojekthi adinga ukusebenza okuphezulu kwezinto.
I-PP inezindleko eziphansi futhi ifanele amaphrojekthi adinga ukusebenza kahle komnotho.
Kafushane, kunomehluko phakathi kwe-PPH ne-PP mayelana nezakhiwo ezibonakalayo, izindawo zokufaka isicelo, amasu okucubungula, nezindleko. Ukukhethwa kwezinto kuncike ezidingweni ezithile zohlelo kanye nezimo zemvelo.
