Uncamathisele ivalvu yakho entsha yePVC kumbhobho, kodwa ngoku iyavuza. Ijoyinti enye ebolileyo ithetha ukuba kufuneka usike umbhobho uze uqale phantsi, uchitha ixesha nemali.

Ukufakela ngokufanelekileyoIvalvu yebhola yePVC, kufuneka usebenzise iprimer ekhethekileyo yePVC kunyeisamente yesinyibilikisiLe ndlela ibandakanya ukusika umbhobho ucocekile, ukususa iimbumbulu, ukugalela i-primer kuzo zombini iindawo, ukufaka isamente, uze emva koko utyhale kwaye ubambe i-joint ngokuqinileyo kangangemizuzwana engama-30 ukwenza i-weld yekhemikhali esisigxina.

Le nkqubo imalunga nokudala ikhonkco leekhemikhali eliqinileyo njengepayipi ngokwayo, kungekuphela nje ngokuncamathisela iindawo. Yingongoma ebalulekileyo endisoloko ndiyigxininisa kumaqabane am, njengoBudi, umphathi wokuthenga e-Indonesia. Abathengi bakhe, ukusuka kubakhi abakhulu ukuya kubathengisi basekuhlaleni, abanakukwazi ukuhlawula ukusilela. Ikhonkco elinye elibi linokuwisa ixesha kunye nohlahlo-lwabiwo mali lweprojekthi. Masihambe ngemibuzo ephambili ukuqinisekisa ukuba yonke into oyisebenzayo iyimpumelelo ehlala ixesha elide.

Uyifaka njani ivalvu yebhola kwipayipi yePVC?

Uneendawo ezifanelekileyo, kodwa uyazi ukuba akukho mathuba esibini ngesamente yePVC. Impazamo enye encinci ithetha ukusika icandelo lombhobho uze uqale phantsi.

Inkqubo yokufakela isebenzisa ukuwelda kwe-solvent kwaye ibandakanya amanyathelo amahlanu abalulekileyo: ukusika isikwere sepayipi, ukususa imiphetho, ukufaka i-primer ye-PVC kwiindawo zombini, ukugquma ngesamente ye-PVC, uze emva koko utyhale iindawo ndawonye ngokujika ikota uze uzibambe ngokuqinileyo.

Ukulungisa le nkqubo yinto eyahlula umsebenzi wobungcali kwingxaki yexesha elizayo. Masihlalutye inyathelo ngalinye ngokweenkcukacha. Le yinkqubo endiyinika abathengi bakaBudi ukuqinisekisa utywino olugqibeleleyo.

1. Sika kwaye Ususe Umonakalo:Qala ngokusika okucocekileyo, okusikwele kumbhobho wakho. Nayiphi na i-engile ingenza umsantsa kwijoyinti. Emva kokusika, sebenzisa isixhobo sokususa iimbumbulu okanye imela elula ukucheba nayiphi na iplastiki ephuma ngaphakathi nangaphandle komphetho wombhobho. Ezi mbumbulu zinokukrwela isamente kwaye zithintele umbhobho ukuba ungahlali ngokupheleleyo.
2. Inkulu:Faka ingubo ye-liberal yeIprimer yePVC(idla ngokuba mfusa) ngaphandle kombhobho nangaphakathi kwesokhethi yevalvu. Musa ukuliphosa eli nyathelo! I-Primer ayisiyonto yokucoca nje kuphela; iqala ukuthambisa iplastiki, iyilungiselela ukuwelda ngamakhemikhali.
3. Isamente:Ngelixa iprimer isemanzi, faka umaleko olinganayo weIsamente yePVCphezu kweendawo ezilungisiweyo. Yifake kumbhobho kuqala, uze unike isokhethi yevalvu uboya obuncinci.
4. Tyhala, Jika & Ubambe:Tyhala umbhobho ngoko nangoko ungene kwisokethi ngokujika okuncinci kwekota. Olu jiko lunceda ukusasaza isamente ngokulinganayo. Emva koko kufuneka ubambe ijoyinti ngokuqinileyo ubuncinane imizuzwana engama-30. I-chemical reaction ivelisa uxinzelelo oluya kuzama ukutyhala umbhobho ubuyele ngaphandle.

Yeyiphi indlela efanelekileyo yokufaka ivalvu yebhola?

Ivalvu ingaphakathi, kodwa isiphatho sibetheka eludongeni. Okanye okubi nangakumbi, ufake ivalvu yomanyano yokwenyani esondele kakhulu kwenye into kangangokuba awukwazi ukufumana isikrufu kwiinati.

"Indlela echanekileyo" yokufaka ivalvu yebhola iqwalasela ukusetyenziswa kwixesha elizayo. Oku kuthetha ukuqinisekisa ukuba isiphatho sinendawo epheleleyo yokujikeleza engama-90 degrees kwaye ii-union nuts kwivalvu yokwenyani ye-union ziyafikeleleka ngokupheleleyo ukuze zigcinwe ixesha elizayo.

Ukufakela ngempumelelo kungaphezulu nje kwe-isitywino esingavuziyo; imalunga nokusebenza kwexesha elide. Kulapho ucwangciso oluncinci lwenza khona umahluko omkhulu. Eyona mpazamo ixhaphakileyo endiyibonayo kukungabikho kocwangciso lokufikelela. Ivalvu yebhola kufuneka ijikeleze iidigri ezingama-90 ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo. Ngaphambi kokuba uvule itini yesamente, bamba ivalvu endaweni yayo kwaye ujike isiphatho kuyo yonke intshukumo yaso. Qinisekisa ukuba ayibetheki eludongeni, kwenye ipayipi, okanye nantoni na enye. Ingongoma yesibini, ngakumbi kwiPntek yethuiivalvu zomanyano lokwenyani, kukufikelela kwiyuniyoni. Inzuzo epheleleyo yoyilo lokwenyani lweyuniyoni kukuba ungayikhulula iyuniyoni kwaye uphakamise umzimba oyintloko ukuze ulungiswe okanye utshintshwe ngaphandle kokusika umbhobho. Ndisoloko ndimkhumbuza uBudi ukuba agxininise oku kubathengi bakhe bekontraka. Ukuba ufaka ivalvu apho ungenakufumana khona isikrufu kwezo nati, usandul' ukuguqula ivalvu yexabiso eliphezulu, elungisekayo ibe yeqhelekileyo, elahlwayo.

Uyiqhagamshela njani ivalvu kumbhobho wePVC?

Ivalvu yakho inemisonto, kodwa umbhobho wakho uthambile. Uzibuza ukuba kufuneka uyincamathisele, uyifake imisonto, okanye ukuba indlela enye ingcono kunenye ukuze uqhagamshele ngamandla.

Kukho iindlela ezimbini eziphambili: ukuwelda i-solvent (ukuncamathisela) ukuze kubekho i-bond esisigxina, edibeneyo, kunye nokuqhagamshelwa ngemisonto kwejoyinti enokwahlulwa. Kwiinkqubo ze-PVC-to-PVC, ukuwelda i-solvent yeyona ndlela inamandla nexhaphakileyo.

Ukukhetha uhlobo loqhagamshelwano olufanelekileyo kubalulekile. Uninzi lweenkqubo zePVC zixhomekeke kwiukuwelda isinyibilikisi, kwaye ngesizathu esivakalayo. Ayizinamathelisi nje kuphela ezi ndawo; izidibanisa ngeekhemikhali zibe yiplastiki enye engenamthungo enamandla kakhulu kwaye ayivuzi. Uqhagamshelo olunemisonto lunendawo yalo, kodwa lukwanobuthathaka. Luluncedo xa uqhagamshela ivalvu yePVC kwipompo yesinyithi okanye itanki esele inemisonto. Nangona kunjalo, uqhagamshelo lweplastiki olunemisonto lunokuba ngumthombo wokuvuza ukuba aluvalwanga kakuhle ngeteyipu yeTeflon okanye intlama. Okubaluleke ngakumbi, ukuqinisa kakhulu intambo yeplastiki eneemisonto yimpazamo eqhelekileyo enokwaphula uqhagamshelo lwabasetyhini, nto leyo ebangela ukungaphumeleli.

Uthelekiso lweNdlela yoQhagamshelo

Ngaba iivalvu zebhola zePVC zibhekiselele kwicala elithile?

Isamente ilungile, kodwa uyathandabuza, ukhangela utolo emzimbeni wevalvu. Ukuncamathisela ivalvu ebhekisa kwicala elingasemva kuya kuba yimpazamo ebiza kakhulu, okuya kukunyanzela ukuba uyitshabalalise.

Hayi, ivalvu yebhola yePVC eqhelekileyo ibhekisa kwicala ngalinye kwaye iya kuyivala kakuhle indlela yokuhamba ukusuka kwelinye icala ukuya kwelinye. Umsebenzi wayo awuxhomekekanga kwindlela yokuhamba. Eyona "ndlela" ibalulekileyo kukuyifakela ukuze ukwazi ukufikelela kwisibambo kunye nee-union nuts.

Lo ngumbuzo omhle obonisa ukucinga ngononophelo. Ulungile ukuba uqaphele, njengoko ezinye iivalvu zijolise ngqo kwicala.ivalvu yokujonga, umzekelo, ivumela ukuhamba kwicala elinye kuphela kwaye iya kuba notolo olucacileyo oluprintiweyo kuyo. Ukuba ifakwe ngasemva, ayizukusebenza. Nangona kunjalo, iiivalvu zebholaUyilo luluqilima. Inebhola enomngxuma odlula kuyo ovala isihlalo. Ekubeni kukho isihlalo kumacala omabini aphezulu nasezantsi, ivalvu iyavalwa ngokugqibeleleyo nokuba amanzi ahamba ngayiphi na indlela. Ngoko ke, awunakuyifakela "ngasemva" ngokubhekiselele ekuhambeni kwamanzi. Njengoko benditshilo ngaphambili, "icala" ekuphela kwalo ekufuneka ukhathazeke ngalo yindlela esebenziseka ngayo ivalvu. Ngaba ungajika isiphatho? Ngaba ungafikelela kwiiyuniyoni? Olu luvavanyo lokwenyani lokufakelwa ngokuchanekileyo kwevalvu esemgangathweni efana naleyo siyivelisayo ePntek.

Isiphelo

Ukuze ufake ivalvu yebhola yePVC efanelekileyo, sebenzisa iprimer kunye nesamente echanekileyo. Cwangcisa ukufikelela kwisibambo kunye ne-union nut ukuqinisekisa uqhagamshelo oluthembekileyo, olungenako ukuvuza, nolunokulungiswa.
