Ukuqiniseka umbono omuhle wokugqamisa kumithambo yezindustria
Ukukhetha indlela yokuxhumana okufanele uma kusakelwa umkhondo wokuxhumana okuphezulu kudinga ukwazi okuphelele ngendlela okwenziwa ngayo amapharti amabili ekhuseleleni emisebenzi yabo. Izindlela ezimbili zokuxhumana ziyasebenza kakhulu ekhaya lomkhondo wokuxhumana xa kusakelwa izikhuluma zama-PVC: ukuxhumana nge-solvent nokuxhumana ngamathread. Amahlayibheli e-engineering nemisakhiwo yamaphathi ayisikhuba kakhulu ngokubhekana kwesikhundla sokuxhumana nge-solvent nokuxhumana ngamathread, ngoba ngisho noma yiliphi indlela inika iziphumo ezihlukene zokuthi zithi zingasemthwakweni kanye nezinqumo zokugcina ngokuphelele kulezi zikhuluma zama-PVC. Ukukhetha indlela engafanele ingalwele isiphumela esiphambili sokuxhumana, izindlela zokungabiyo zokusebenza, nokuphula kwezinhlelo zokuphatha izinto ngokuphelele ekhaya lomkhondo wokuxhumana. Ngakho-ke, ngokwamanje, abanye amaprojekthi abadinga ukuxhumana okuphambili, okungayikwazi ukuzigqibela, ngokuxhumana nge-solvent, kodwa abanye bavumelela kakhulu ngokuhlanganisa nokuvumela ukuzilungiselela okunikezwa ngokuxhumana ngamathread. Ukubheka izinto ezithile njengephazimba lokushisa, izinguquko zokushisa, nokuthi kungaba khona ukuguqula kwezinhlelo zokuxhumana kusiza ukuphatha ukuthi ukuxhumana nge-solvent noma ukuxhumana ngamathread kuyizokwenzela iziphumo eziphezulu kwezikhuluma zama-PVC ezinkulu.
Ukuthuthukiswa kwezinto zokusebenza nokuphelele kwezinkqubo zokugcina izinhlobo zemithambo
Ezakhiweni ezidinga uphawu oluhlala njalo, olungafihli lutho olungamelana nengcindezi ephezulu, ukuhlanganisa izixazululo kuyindlela engcono kakhulu. Inqubo yokuhlanganisa izixazululo idlula ukunamathela okulula; isebenzisa i-priming ekhethekile yamakhemikhali nesimende esixazululayo ukuze incibilikise izingqimba eziphezulu zepulasitiki kokubili ipayipi nokufakwa kwe-PVC. Njengoba amakhemikhali eba manzi, amaketanga e-polymer ayahlangana futhi ahlangane, ngokuyisisekelo akha ucezu olulodwa lwepulasitiki oluqhubekayo ngokuhlangana kwe-solvent. Lesi sibopho esingakholeki esingamakhemikhali siqinisekisa ukuthi ukuhlangana kwe-solvent kunikeza ukumelana okuvelele nengcindezi yangaphakathi, ukushaywa ngamanzi, nokudlidliza kwemishini kuzo zonke izihlanganisi ze-PVC. Ukuhlanganisa kahle amapayipi ngesivimbeli kudinga ukulungiswa ngokucophelela, kuhlanganise nokusika isikwele sepayipi, ukuwasusa kahle amagquma nokufaka izingxenye ngaphakathi kwefasitela elifanele lokuziphendukela kwemvelo. Ukukhiqiza ngokunemba okukhulu kubalulekile lapha, njengoba ukubekezelelana okuqinile kuma-fittings e-PVC kuvimbela izikhala ezingase zibuthakathaka ngokuhlangana kwe-solvent-bonded phakathi neminyaka yokusebenza kwezimboni ezinzima, okwenza ukubopha kwe-solvent kuthembeke kakhulu.
Ukuchaza ukuthi i-mechanical threads ziyathola kanjani nokuthi zisebenza kanjani
Kunye nako, izihlanganisi zesithelo zisiza ngokwemvelo nokuziphatha kahle uma umkhakha wokugcina kufune ukuzibophezwa kahle, ukuboniswa, noma ukuguqulwa kwamanje. Ngaphandle kokuba kuyinto eyodwa yokuqondisa isithelo, izihlanganisi zesithelo zisebenza ngamathreadi amadala nezithelo, okunjalo kusukela kwe-polytetrafluoroethylene tape noma izihlanganisi zesithelo esithile ukuze kuvaleke ukuphuma kwamaflo ayisikhathi esikhundleni sesihlanganisi se-PVC. Ukusebenzisa izihlanganisi zesithelo kuyisivumelwano esihle kakhulu kumikhiyana eminingi apho izivali, izimitha, noma izipampu kufanele kubhekwe ngokuphelele futhi kubuyiselwe ngokuphelele ngaphandle kokukhupha kumkhakha osebengqondile. Kepha, ukusebenzisa izihlanganisi zesithelo kufanele kubhekwe ngokujabula kakhulu ngokugcina, ngoba amathreadi amasipho ayisikhathi asizwa ngokungafani, ukuphakanyiswa, noma ukubeka phakade kakhulu. Uma umsebenzisi abeka ubukhulu obukhulu kwezihlanganisi zesithelo, ubukhulu bokubeka phakade kungabangela ukuthi izihlanganisi zesithelo ze-PVC zihlabe. Lokhu-ke kuyisizinda sokuthi ukuthenga kwezinsiza nezinhlobo ezinkulu zokubeka phakade kuyisizinda esifanele kakhulu kwezihlanganisi zesithelo, ukuze lezi zihlanganisi zokwenza ngokomthetho nezinye izicelo ze-PVC zibe nesibonelelo sokubaluleka ngokwesikhundla ngokubeka phakade.
Imithambo Yokusebenza Kwemithambo Yokuqonda Nokuthi Kuphakanyiswa Kwemithambo
Lapho kuhlaziywa amamethrikhi okusebenza kwezobuchwepheshe achazwe yizindinganiso zezimboni zomhlaba wonke, umehluko ongokomzimba phakathi kokuxhuma izixazululo nokuxhuma okugoqiwe uba sobala kakhulu. Izinkombandlela zobunjiniyela ezijwayelekile zibonisa ukuthi ukuhlangana okuhlanganiswe kahle okuhlanganiswe nesixazululo kufinyelela ekucindezelweni okuphelele okulingana nepayipi ngokwalo, okwenza ukuhlanganiswa kwesixazululo kube yisilinganiso semigqa yokuhambisa eyinhloko ephezulu. Ngakolunye uhlangothi, ukusebenzisa izixhumi ezinemichilo kunciphisa amandla okucindezela ohlelweni, ngoba ukusika noma ukubumba imicu odongeni lwethumbu kunciphisa ubukhulu bayo obusebenzayo. Ukuhlolwa kwembula ukuthi izixhumi ezinezintambo nazo zikhungathekile kakhulu ekukhathaleni kwesakhiwo okubangelwa ukudlidliza okuqhubekayo kokusebenza uma kuqhathaniswa nokuxhuma okuyindilinga okutholakala ngokuxhuma okuncibilikisayo. Ngenxa yalezi zizathu, abaklami bezinhlelo abanolwazi ngokuvamile banciphisa ukuxhumana okuxhunyiwe emigqeni yokusiza engaphansi kwengcindezi noma ezindaweni ezifinyeleleka kalula, ngenkathi bethembela emandleni aphakeme okubopha izixazululo ezingxenyeni ezibucayi ezisebenzisa izinto zokulungisa ze-PVC ezisezingeni
Ukukhetha Indlela Eyo Yodwa Yokuthintana Kwesikhathi Esidlongwe
Ekugcineni, ukulinganisela amandla okuhlanganisa izixazululo nokuxhuma okugoqekile kudinga ukubuka okuphelele izidingo zesicelo esithile kanye necebo lokugcina isikhathi eside lohlelo lokuphathwa koketshezi. Izinhlelo eziningi ezithuthukile empeleni zisebenzisa indlela ye-hybrid, ehlanganisa amandla angapheli okubopha i-solvent yamakhanda amakhulu nokusebenza okusebenzayo kokuxhumeka okugoqekile ekuxhumeni kwemishini. Ukuthenga lezi zingxenye kumkhiqizi onokwethenjelwa onekhono lokukhiqiza eliphambili kuqinisekisa ukuthi kokubili ukuhlanganisa izixazululo nokuxhuma okugoqekile kusebenza kahle. Yilapho i-BSX inikeza khona inani elihlukile, isebenzisa ubuchwepheshe obusezingeni eliphezulu bokubumba ngomjovo kanye neketanga lokuhlinzeka lomhlaba wonke eliqinile ukuhlinzeka ngemishini ephezulu ye-PVC edlula izindinganiso zomhlaba wonke eziqinile. Kungakhathaliseki ukuthi iphrojekthi incike ekuhlanganisweni kwamakhemikhali kokuxhuma izixazululo noma ekuzivumelaneni nezimo kwemishini yokuxhuma okuxhunyiwe, ubuchwepheshe obuqondile kanye namandla amakhulu okukhiqiza asekela i-BSX aqinisekisa ukuphepha okuphezulu kokusebenza, ukuqina kwesikhathi eside, nokuhlanganiswa okungenamthungo kw
