Yenziwa kanjani i-Rubber Tubing

Amashubhu erabhaihluke ngokuhlukile kwamanye amashubhu ngenxa yokuqukethwe kwenjoloba, okuyi-elastomer enamandla amakhulu nokuqina kanye nokukwazi ukwelulwa nokukhubazeka ngaphandle kokulimala unomphela.Lokhu kubangelwa ikakhulukazi ukuguquguquka kwayo, ukumelana nokukhala, ukuqina, nokuzinza kokushisa.
Amashubhu enjoloba akhiqizwa kusetshenziswa izinqubo ezimbili.Indlela yokuqala ukusetshenziswa kwe-mandrel, lapho imichilo yenjoloba isongwe ngepayipi futhi ifudunyezwe.Inqubo yesibili i-extrusion, lapho irabha iphoqelelwa nge-die.

KanjaniI-Rubber TubingKwenziwe?

Inqubo ye-Mandrel
I-Rubber Roll
Irabha esetshenziselwa ukwenza amashubhu enjoloba kusetshenziswa inqubo ye-mandrel ilethwa ukuze kukhiqizwe imiqulu yemigqa yenjoloba.Ubukhulu bezindonga ze-tubing bunqunywa ubukhulu bamashidi.Umbala we-tubing unqunywa umbala we-roll.Nakuba umbala ungadingeki, usetshenziswa njengendlela yokunquma ukuhlukaniswa kanye nokusetshenziswa kokugcina kweshubhu yenjoloba.

Ukugaya
Ukwenza irabha ikwazi ukuphenduleka kunqubo yokukhiqiza, iqhutshwa ngesigayo esishisisa imicu yenjoloba ukuze ithambe futhi ibushelelezi irabha ukuze kuqinisekiswe ukuthi inokwakheka okulinganayo.

Ukusika
Irabha ethambile futhi ethambile ithuthelwa emshinini wokusika owusika ube yimichilo yobubanzi obulinganayo ukuze uvumelane nobubanzi nobukhulu bobukhulu beshubhu yenjoloba okufanele yenziwe.

UMandrel
Amapheshana adalwe ekusikeni athunyelwa ku-mandrel.Ngaphambi kokugoqa imichilo ku-mandrel, i-mandrel igcotshiwe.Ububanzi be-mandrel yizilinganiso eziqondile njenge-bore ye-tubing yenjoloba.Njengoba i-mandrel iphenduka, imichilo yenjoloba isongelwe ngokulinganayo futhi ejwayelekile.

Inqubo yokugoqa ingase iphindwe ukuze kufinyelele ubukhulu obufunekayo beshubhu lerabha.

Isendlalelo Sokuqinisa
Ngemva kokuba ishubhu lifinyelele ubukhulu obuqondile, isendlalelo sokuqinisa siyengezwa esenziwe ngezinto zokwenziwa zamandla amakhulu ezifakwe ngenjoloba.Ukukhethwa kwesendlalelo kunqunywa inani lokucindezela ishubhu lerabha elingabekezelela.Kwezinye izimo, ukuze uthole amandla engeziwe, isendlalelo sokuqinisa singase sengezwe ucingo.

Isendlalelo Sokugcina
Isendlalelo sokugcina sokukhumula iraba isembozo sangaphandle.

Ukuthepha
Uma zonke izingqimba ezihlukahlukene zemichilo yerabha sezisetshenzisiwe, ubude obugcwele beshubhu eliqediwe bugoqwe ngetheyiphu enayiloni emanzi.I-tape izoncipha futhi icindezele izinto ndawonye.Umphumela wokugoqa itheyiphu wukuqedwa okuthungwe kububanzi obungaphandle (OD) beshubhu okuba yimpahla nenzuzo yezinhlelo zokusebenza lapho kuzosetshenziswa khona ishubhu.

I-Vulcanization
I-tubing ku-mandrel ibekwe ku-autoclave yenqubo ye-vulcanization ephulukisa irabha, eyenza ibe nokunwebeka.Uma ukuvuthwa sekuqediwe, itheyiphu enayiloni eshwabene iyasuswa.

Ukususa ku-Mandrel
Umkhawulo owodwa weshubhu uvalwe ngokuqinile ukuze udale ingcindezi.Kwenziwa imbobo kushubhu ukuze amanzi aphonswe ukuze ahlukanise ishubhu lenjoloba ku-mandrel.Ishubhu yenjoloba ishelela kalula ku-mandrel, iziphetho zayo zisikiwe, futhi zisikwe ngobude obufunayo.

Indlela ye-Extrusion
Inqubo ye-extrusion ihlanganisa ukuphoqelela irabha nge-disc emise okufa.Ishubhu lerabha elenziwe yinqubo ye-extrusion isebenzisa inhlanganisela yenjoloba ethambile engavulwanga.Izingxenye ezikhiqizwa kusetshenziswa le ndlela zithambile futhi ziyathandeka, ezivuvukala ngemuva kwenqubo yokukhipha.

Ukondla
Inqubo ye-extrusion iqala ngokuthi inhlanganisela yerabha idliwe ku-extruder.

Isikulufu Esijikelezayo
Inhlanganisela yerabha kancane ishiya okokuphakelayo futhi idliswa kusikulufu esiyihambisa eduze nedayisi.

I-Rubber Tubing Die
Njengoba impahla yerabha eluhlaza inyakaziswa yisikulufu, iphoqelelwa ngedayizi ngezilinganiso eziqondile zobubanzi nobukhulu beshubhu.Njengoba irabha isondela eduze nokufa, kuba khona ukwanda kwezinga lokushisa nokucindezela, okubangela ukuthi impahla ye-extruder ivuvuke kuye ngohlobo lwenhlanganisela nobulukhuni.

I-Vulcanization
Njengoba irabha esetshenziswa enqubweni ye-extrusion ingavulwanga, kufanele ibhekane nohlobo oluthile lwe-vulcanization uma isidlulile ku-extruder.Nakuba ukwelashwa ngesulfure kwakuyindlela yokuqala yokuvuvukala, ezinye izinhlobo ziye zathuthukiswa ukukhiqizwa kwesimanje, okuhlanganisa ukwelapha nge-microware, okugeza kukasawoti, noma ezinye izinhlobo zokushisisa.Inqubo iyadingeka ukuze unciphise futhi uqinise umkhiqizo ophelile.
I-vulcanization noma inqubo yokwelapha ingabonakala kumdwebo ongezansi.
