Ukeneye valve yo gukoresha chemical line, ariko PVC isanzwe ntabwo ari amahitamo. Guhitamo ibikoresho bibi bishobora gutera amazi ava, gusuka nabi, ndetse no kwangiza imikorere y’umubiri wawe wose.

Valve y'umupira wa PP ni valve ifunga ikozwe muri polypropylene, polymeri ya thermoplastic. Yatoranijwe by'umwihariko kubera ko irwanya aside nyinshi, bases, na chemical solvents, cyane cyane aho PVC yananirwa.

Iyo mvuganye n'abafatanyabikorwa banjye nka Budi muri Indoneziya, ikiganiro gikunze kurenga ikoreshwa ry'amazi asanzwe. Abakiriya be benshi bakora mu nganda nko gutunganya imiti cyangwa gutunganya amazi, aho amazi aba akomeye cyane kurusha amazi asanzwe. Kuri iyi mirimo, gukoresha amazi asanzwe gusa.Valve ya PVCNtabwo bihagije. Ukeneye ibikoresho byubatswe kugira ngo bihangane n'imimerere mibi idasenyuka. Ibyo bikoresho akenshi biba ari polypropylene, cyangwa PP. Bitanga umutekano n'ubwirinzi bikenewe muri izi nganda.

Ni iyihe miterere yuzuye ya PP muri valves?

Ubona "PP" iri ku rutonde ariko ntuzi neza icyo isobanura. Ibi bituma bigorana gushaka imitungo yayo cyangwa gusobanurira abakiriya bawe ibyiza byayo mu buryo bwizewe.

Ubwoko bwuzuye bwa PP muri valves ni Polypropylene. Ni thermoplastic ikomeye cyane kandi yoroheje iri mu muryango umwe wa pulasitiki nka PVC (Polyvinyl Chloride) na PE (Polyethylene).

Polypropylene ni imwe muri pulasitiki zishobora gukoreshwa cyane ku isi. Ni ibikoresho bikoreshwa mu bintu byose kuva ku bice by'imodoka kugeza ku bikoresho bya laboratwari kubera imiterere yayo yihariye. Mu isi y'amavali n'imiyoboro, inyungu yayo nyamukuru ni uko itangaje.kurwanya imitiBitandukanye na PVC, ishobora guhangana n'aside nyinshi zikomeye, alkali, n'ibintu bishongesha ibinyabuzima bitangiritse. Niyo mpamvu twebwe muri Pntek dufite umurongo wihariye waVali za PPTuzi ko ku mirimo imwe n'imwe y'inganda, nta cyasimbura. Kumva ko "PP" bivuze polypropylene ni intambwe ya mbere yo guhitamo valve ikwiye yo gukoresha imiti ikomeye.

Polypropylene (PP) ugereranije na Polyvinyl Chloride (PVC)

Umutungo	Polypropylene (PP)	Polyvinyl Chloride (PVC)
Izina ry'Ikintu	Polypropylene	Polyvinyl Chloride
Ikoreshwa ry'ibanze	Inganda zikora imiti, laboratwari, amashanyarazi, ikoreshwa mu nganda.	Ubwikorezi bw'amazi, kuhira, amazi yo mu ngo, pisine.
Ubudahangarwa bw'ibinyabutabire	Ni byiza cyane; cyane cyane mu kurwanya aside, bases, n'ibintu bishongesha.	Ni byiza; ariko ishobora kwibasirwa n'ibintu bimwe na bimwe byangiza imiterere y'umubiri n'ibindi binyabutabire birimo chlorine.
Ubushyuhe ntarengwa	Hejuru; akenshi ishobora gufata amazi kugeza kuri 80-90°C (175-195°F).	Hasi; ubusanzwe ubushyuhe bugarukira kuri 60°C (140°F).
Uburyo bwo guhuza	Guhuza ubushyuhe (gusudira) ni ibintu bisanzwe, kandi biboneka hamwe n'ibice/imigozi	Sima ishongesha (gushyiramo kole) ku mpera z'isoko, gukurura ubudodo.

Umupira wa PP ni iki?

Ubona valve ifite umubiri wa PVC ariko umupira wa PP. Uru ruvange rw'ibikoresho bisa n'ibidasanzwe, ukibaza niba ari uburyo bwo kugabanya ikiguzi cyangwa ari ikintu gifite intego nyayo.

Umupira wa PP ni uruziga ruzenguruka ruri imbere muri vali ikozwe muri polypropylene. Gukoresha umupira wa PP muri vali ya PVC ni amahitamo meza yo gushushanya atuma habaho ubudahangarwa bw'imiti mu gice cy'imbere cya vali kandi bigatuma ikiguzi kigabanuka.

Iyi ni ingingo ikunze kuganirwaho. Umupira n'intebe ni ibice bya valve bihora bihura n'amazi, ndetse n'igihe valve ifunze. Byitwa "ibice bitose"Ku rundi ruhande, igice cy'umugozi gishyirwa ahagaragara gusa iyo umugozi ufunguye. Ku bijyanye no gukoresha amazi yangiza buhoro, ushobora kudakenera ko igice cy'umugozi cyose gikorwa mu bikoresho bihenze kandi byo mu rwego rwo hejuru. Ukoreshejeumupira wa PP urwanya imitiimbere mu mubiri usanzwe wa PVC, dukora uburyo buhendutsevalveibyo biracyatanga uburinzi burushijeho kuba bwiza aho ari ngombwa cyane. Ni ugutanga igisubizo cyihariye gihuza imikorere n'ingengo y'imari ijyanye n'ibyo abafatanyabikorwa bacu bakeneye.

Igipimo cy'umuvuduko wa valve y'umupira wa PP ni ikihe?

Uzi ko PP ari nziza ku miti, ariko se ishobora guhangana n'umuvuduko? Gukoresha valve idahabwa agaciro ni ikibazo gikomeye ku mutekano gishobora gutuma sisitemu ikwirakwira ndetse n'imiti isuka nabi.

Igipimo cy'umuvuduko ku mashini za Pntek's PP ball valves ni PN16, ari yo 16 bar cyangwa hafi 235 PSI ku bushyuhe bw'icyumba (20°C). Ni ngombwa kwibuka ko iki gipimo kigabanuka uko ubushyuhe bw'amazi bwiyongera. Buri gihe reba imbonerahamwe y'umuvuduko n'ubushyuhe by'uwakoze.

IbyacuVali z'umupira za PPMuri Pntek bafite amanota meza ya PN16. Ibi bivuze ko bashobora kwihanganira umuvuduko wa bar 16, ari wo 235 PSI. Iri suzuma riri hejuru ni ikimenyetso cy'ubwiza bw'inganda, ariko si inkuru yuzuye. Ikintu cy'ingenzi nasobanurira abafatanyabikorwa nka Budi ni uko iri suzuma ry'umuvuduko rifitanye isano itaziguye n'ubushyuhe bw'amazi. Teroplasitiki zose, harimo na polypropylene, zirushaho koroha kandi zikagabanuka uko zirushaho gushyuha. Uko ibikoresho bigenda byoroha, ubushobozi bwabyo bwo gukumira umuvuduko bugabanuka cyane. Kwirengagiza iyi curve 'yo kugabanya' si ingeso mbi gusa; ni akaga. Dutanga imbonerahamwe isobanutse neza hamwe na valve zacu kugira ngo hirindwe ko sisitemu yangirika kandi tukareba neza ko umutekano w'abakiriya bacu ari wo uza ku isonga.

Uruhare rw'ingenzi rwo kugabanya ubushyuhe

Ubushyuhe bw'amazi	Umuvuduko ntarengwa w'imikorere (valve ya PN16)
Ubushyuhe bugera kuri 20°C (68°F)	Udupapuro 16 (235 PSI)
Ubushyuhe bwa 60°C (140°F)	Umwanya wa 6.4 (94 PSI)
Ubushyuhe bugera kuri 80°C (176°F)	Umwanya wa 3.2 (47 PSI)

Icyitonderwa: Uru ni urugero rwa valve ya PN16. Buri gihe reba urupapuro rw'amakuru rwa Pntek kugira ngo ubone imibare nyayo.

Valve ya PP-H ni iki?

Uhura n'ubwoko butandukanye bwa PP, nka “PP-H.” Ntuzi neza icyo “-H” bivuze cyangwa niba ari ikindi kintu ugomba guhangayikishwa nacyo mugihe utumiza.

Valve ya PP-H ikozwe muri Polypropylene Homopolymer. Iyi ni urwego rwihariye kandi rukomeye rwa PP ruzwiho gukomera kwayo, gukomera kwayo, n'imikorere yayo ikora neza cyane, bigatuma iba nziza cyane ku mavali n'ibikoresho byo mu nganda.

Polypropylene yose si ko ingana. "-H" isobanura Homopolymer, bivuze ko pulasitiki ikozwe mu bwoko bumwe gusa bwa monomer building block (propylene). Ibi bivamo ibikoresho bikomeye cyane kandi bikomeye, ari nabyo wifuza ku mubiri wa valve ugomba kuba ufite umuvuduko mwinshi kandi urwanya guhinda. Hari ubundi bwoko, nka copolymers (PP-B, PP-R), bukorwa hiyongereyeho indi monomer. Ubu bwoko bundi bworoshye cyangwa bufite imbaraga nziza ku bushyuhe buke, bigatuma bukwiriye ibindi bintu, nk'imiyoboro igomba guhindagurika. Muri Pntek, duhitamo PP-H ku mavali yacu yo mu nganda kuko gukomera kwayo no kudashyuha bitanga imikorere myiza kandi bimara igihe kirekire.

Ubwoko busanzwe bwa Polypropylene

Ubwoko	Izina ryuzuye	Imiterere y'ingenzi	Isanduku nziza yo gukoresha
PP-H	Homopolimeri	Ubukomere bwinshi, imbaraga, kurwanya ubushyuhe n'imiti mu buryo bwiza.	Valves, ibikoresho by'inganda, ibigega bya shimi.
PP-B	Kopolimeri y'amaboko	Imbaraga nyinshi z'impanuka, cyane cyane iyo ubushyuhe buri hasi.	Amabati, ibice by'inganda bikeneye gukomera.
PP-R	Kopolimeri idasanzwe	Yoroshye, yoroshye kandi irinda ubushyuhe igihe kirekire.	Imiyoboro y'amazi ashyushye n'akonje.

Umwanzuro

A Valve y'umupira wa PPni ingenzi cyane mu gucunga imiti mu buryo bwizewe. Usobanukiwe imiterere yayo, umuvuduko wayo, n'ibipimo bitandukanye nka PP-H, ushobora guhitamo valve ikwiye yo gukora imirimo isaba imbaraga nyinshi mu nganda.
