Uragerageza gutumiza valve, ariko uwabitanze umwe abita PVC undi abita UPVC. Uru rujijo rugutera guhangayikishwa no kugereranya ibicuruzwa bitandukanye cyangwa kugura ibikoresho bitari byo.

Kumupira wumupira ukomeye, nta tandukaniro rifatika riri hagati ya PVC na UPVC. Amagambo yombi yerekeza kuri kimweibikoresho bya polyvinyl chloride idafite amashanyarazi, irakomeye, irwanya ruswa, kandi nziza kuri sisitemu y'amazi.

Iki nikimwe mubibazo bikunze kubona, kandi bitera urujijo bitari ngombwa murwego rwo gutanga. Mperutse kuvugana na Budi, umuyobozi ushinzwe kugura ibicuruzwa byinshi muri Indoneziya. Abaguzi be bashya bato barikomye, bibwira ko bakeneye isoko yubwoko bubiri butandukanye. Namusobanuriye ko kuri valve zikomeye dukora kuri Pntek, no mubice byinshi byinganda, amazina akoreshwa muburyo bumwe. Gusobanukirwa impamvu bizaguha ikizere mubyemezo byawe byo kugura.

Haba hari itandukaniro hagati ya PVC na UPVC?

Urabona amagambo ahinnye abiri kandi mubisanzwe ukeka ko ahagarariye ibikoresho bibiri bitandukanye. Uku gushidikanya kurashobora kudindiza imishinga yawe mugihe ugerageza kugenzura neza.

Icy'ingenzi, oya. Mu rwego rwimiyoboro ikomeye na valve, PVC na UPVC nimwe. "U" muri UPVC bisobanura "udafite amashanyarazi," usanzwe ari ukuri kubintu byose bikomeye bya PVC.

Urujijo ruva mumateka ya plastiki. Polyvinyl chloride (PVC) nibikoresho fatizo. Kugirango ihindurwe kubicuruzwa nka shitingi yubusitani cyangwa insinga zamashanyarazi, abayikora bongeramo ibintu bita plastike. Gutandukanya imiterere yumwimerere, itajegajega na verisiyo yoroheje, ijambo "ridashyizwemo" cyangwa "UPVC" ryagaragaye. Ariko, kubisabwa nka sisitemu y'amazi akandamijwe, ntushobora gukoresha verisiyo yoroheje. Imiyoboro yose ikomeye ya PVC, fitingi, hamwe numupira wumupira, kubwimiterere yabyo, idashyizwe mubikorwa. Mugihe rero, mugihe ibigo bimwe byandika ibicuruzwa byabo "UPVC" kugirango bisobanuke neza, naho ibindi bigakoresha gusa "PVC," baba bashaka kuvuga ibintu bimwe bikomeye, bikomeye. Kuri Pntek, turabahamagara gusaPVC imipirakuko nijambo risanzwe, ariko zose ni tekinike UPVC.

Ese imipira ya PVC nibyiza?

Urabona ko PVC ari plastike kandi igura munsi yicyuma. Ibi bigutera kwibaza ubuziranenge bwayo ukibaza niba biramba bihagije kubikorwa byawe bikomeye, birebire.

Nibyo, ubuziranenge bwa PVC imipira yumupira nibyiza kubyo bagenewe. Zirinda ingese no kwangirika, zoroheje, kandi zitanga ubuzima burambye mugukoresha amazi akonje, akenshi ziruta icyuma.

Agaciro kabo ntabwo kari mubiciro byabo gusa; ni mumikorere yabo mubidukikije byihariye. Ibyuma byuma, nkumuringa cyangwa icyuma, bizangirika cyangwa byangirika mugihe, cyane cyane muri sisitemu zifite amazi yatunganijwe, amazi yumunyu, cyangwa imiti imwe n'imwe. Iyi ruswa irashobora gutuma valve ifata, bigatuma bidashoboka guhinduka mugihe cyihutirwa. PVC ntishobora kubora. Ifite imiti yongeramo amazi menshi, umunyu, na acide yoroheje. Niyo mpamvu abakiriya ba Budi mu nganda z’amafi y’inyanja muri Indoneziya bakoresha gusa ububiko bwa PVC. Amazi yumunyu yasenya ibyuma byicyuma mumyaka ibiri gusa, ariko ububiko bwa PVC bukomeje gukora neza mumyaka icumi cyangwa irenga. Kubisabwa byose munsi ya 60 ° C (140 ° F), aPVC umupirantabwo ari uburyo "buhendutse" gusa; akenshi ni amahitamo yizewe kandi maremare kuko ntazigera afata ruswa.

Nubuhe bwoko bwiza bwumupira wumupira?

Ushaka kugura valve "nziza" kugirango umenye ko sisitemu yawe yizewe. Ariko hamwe nibikoresho byinshi biboneka, guhitamo ibyiza byuzuye umuntu yumva birenze kandi bishobora guteza akaga.

Ntamupira numwe "mwiza" wumupira kumurimo wose. Umuyoboro mwiza niwo ufite ibikoresho n'ibishushanyo bihuye neza n'ubushyuhe bwa sisitemu, umuvuduko, n'ibidukikije.

“Ibyiza” buri gihe ugereranije no gusaba. Guhitamo ibitari byiza ni nko gukoresha imodoka ya siporo mu gutwara amabuye-ni igikoresho kitari cyiza ku kazi. Umuyoboro w'icyuma udafite ingese ni mwiza cyane ku bushyuhe bwinshi no ku muvuduko mwinshi, ariko birahenze cyane birenze urugero kuri sisitemu yo kuzenguruka ikidendezi, aho valve ya PVC isumba bitewe naKurwanya chlorine. Buri gihe nyobora abafatanyabikorwa bacu gutekereza kubintu byihariye byumushinga wabo. Umuyoboro wa PVC ni nyampinga wa sisitemu y'amazi akonje kubera kurwanya ruswa hamwe nigiciro. Ku mazi ashyushye, ugomba kuzamukaCPVC. Kuri gaze cyangwa amavuta yumuvuduko mwinshi, umuringa ni amahitamo gakondo, yizewe. Kubikoresho byo murwego rwohejuru cyangwa imiti yangirika cyane, ibyuma bidafite ingese birakenewe. Guhitamo "byiza" mubyukuri nibyo bitanga umutekano ukenewe no kuramba kubiciro byose.

Umupira wo Kuringaniza Ibikoresho

Ni irihe tandukaniro riri hagati ya PVC U na UPVC?

Mugihe utekereje ko usobanukiwe na PVC na UPVC, urabona "PVC-U" ku nyandiko ya tekiniki. Iri jambo rishya ryongeyeho urundi rwego rwo kwitiranya ibintu, bigatuma ugira kabiri ukeka ko ubyumva.

Nta tandukaniro na gato. PVC-U nubundi buryo bwo kwandika uPVC. “-U” nayo isobanura idafite amashanyarazi. Ni amasezerano yo kwita izina akunze kugaragara muburayi cyangwa mpuzamahanga (nka DIN cyangwa ISO).

Bitekerezeho nko kuvuga “amadorari 100” na “amafaranga 100.” Ni amagambo atandukanye kubintu bimwe. Mwisi yisi ya plastiki, uturere dutandukanye twateje imbere uburyo butandukanye bwo kuranga ibi bikoresho. Muri Amerika ya Ruguru, “PVC” ni ijambo risanzwe rikoreshwa mu muyoboro ukomeye, kandi “UPVC” rimwe na rimwe rikoreshwa mu kumvikana. Mu Burayi no mu rwego mpuzamahanga, “PVC-U” ni ijambo ry’ubuhanga risanzwe ryerekana “ridashyizwe mu bikorwa.” Kubaguzi nka Budi, iki nikintu gikomeye cyamakuru kumurwi we. Iyo babonye isoko ryiburayi ryerekana ububiko bwa PVC-U, bamenye bafite ikizere ko indangagaciro za PVC zisanzwe zujuje ibisabwa neza. Byose bimanuka kubintu bimwe: vinyl polymer itajegajega, ikomeye, idashyizwemo plastike itunganijwe neza. Ntugafatwe mu nzandiko; wibande kumiterere yibikoresho nibipimo ngenderwaho.

Umwanzuro

PVC, UPVC, na PVC-U byose bivuga ibintu bimwe bikomeye, bidashyizwe mubikorwa byiza byumupira wamaguru ukonje. Amazina atandukanye ni amahame yakarere cyangwa amateka gusa.
