Yenziwa njani i-Rubber Tubing

Ityhubhu yerabhayahluke ngokuhlukileyo kwezinye iityhubhu ngenxa yomxholo wayo werabha, eyi-elastomer enamandla amakhulu kunye nokuqina kunye nokukwazi ukolulwa kunye nokukhubazeka ngaphandle kokonakala ngokusisigxina.Oku kubangelwa ikakhulu ngenxa yokuguquguquka kwayo, ukuxhathisa ukukrazula, ukomelela, kunye nokuzinza kwe-thermal.
Iityhubhu yerabha iveliswa kusetyenziswa enye yeenkqubo ezimbini.Indlela yokuqala kukusetyenziswa kwe-mandrel, apho imicu yerabha ijikelezwe ngombhobho kwaye ifudunyezwe.Inkqubo yesibini yi-extrusion, apho irabha inyanzeliswa ngokufa.

NjaniI-Rubber TubingYenziwe?

Inkqubo Mandrel
Umqulu werabha
Irabha esetyenziselwa ukwenza ityhubhu yerabha kusetyenziswa inkqubo ye-mandrel ihanjiswa kwimveliso kwimiqulu yerabha yemicu.Ubunzima beendonga ze-tubing bunqunywe ngubukhulu bamaphepha.Umbala we-tubing unqunywe ngumbala we-roll.Nangona umbala ungeyomfuneko, usetyenziswa njengendlela yokwenza isigqibo sokuhlelwa kunye nokusetyenziswa kokugqibela kwetyhubhu yerabha.

Ukugaya
Ukwenza irabha ikwazi ukuphepheka kwinkqubo yokuvelisa, iqhutywa kwilitye lokusila elifudumeza imicu yerabha ukuze ithambe kwaye igudise irabha ukuqinisekisa ukuba inokwakheka okulinganayo.

Ukusika
I-rubber ethambileyo kunye ne-pliable ihanjiswe kumatshini wokusika owunqumle ube yimichilo yobubanzi obulinganayo ukuze uvumelane nobubanzi kunye nobukhulu bobukhulu betyhubhu yerabha ekufuneka yenziwe.

Mandrel
Imicu ezidalwe ukusika zithunyelwa kwi mandrel.Ngaphambi kokuba usonge imicu kwi mandrel, mandrel lubricated.Ububanzi be mandrel imilinganiselo ngqo njengoko bore of ityhubhu irabha.Njengoko i-mandrel ijika, imicu yerabha ijikelezwe ngesantya esilinganayo kunye nesiqhelo.

Inkqubo yokusonga ingaphinda ifikelele kubukhulu obufunwayo betyhubhu yerabha.

UQeqesho lokuQinisa
Emva kokuba i-tubing ifikelele kubukhulu obuchanekileyo, i-reinforcement layer yongezwa eyenziwe yinto yokwenziwa yamandla aphezulu efakwe irabha.Ukukhethwa koluhlu kunqunywe ngumlinganiselo woxinzelelo i-rubber tubing inokunyamezela.Kwezinye iimeko, ukomelela okongeziweyo, umaleko wokuqinisa unokuba nocingo olongeziweyo.

Uluhlu lokugqibela
Umaleko wokugqibela wokuhlutywa kwerabha sisigqubuthelo sawo sangaphandle.

Ukucofa
Nje ukuba zonke iileya ezahlukeneyo zemicu yerabha isetyenzisiwe, ubude obupheleleyo betyhubhu egqityiweyo zisongelwe ngeteyiphu yenayiloni emanzi.I-tape iya kuncipha kwaye icinezele izinto kunye.Isiphumo sokusonga iteyiphu kukugqitywa kwe-textured kwi-diameter yangaphandle (OD) ye-tubing eba yi-asethi kunye nenzuzo yezicelo apho i-tubing iya kusetyenziswa.

Vulcanization
Ityhubhu kwi mandrel ibekwe i autoclave inkqubo vulcanization ephilisa irabha, leyo eyenza ibe elastic.Nje ukuba ivulcanization igqityiwe, iteyiphu yenayiloni eshwabeneyo iyasuswa.

Ukususa kwi Mandrel
Esinye isiphelo setyhubhu sitywinwe ngokuqinileyo ukudala uxinzelelo.Kwenziwa umngxuma kwityhubhu ukuze amanzi ampompelwe ukwahlula irubha kwi-mandrel.Ityhubhu yerabha ityibilika ngokulula kwi-mandrel, iziphelo zayo zilungisiwe, kwaye zinqunyulwa ubude obufunwayo.

Indlela Yokukhupha
Inkqubo ye-extrusion ibandakanya ukunyanzeliswa kwerabha ngediskhi emile.Irubha ityhubhu eyenziwe yinkqubo ye-extrusion isebenzisa ikhompawundi ethambileyo yerabha engavulwanga.Iinxalenye eziveliswe ngokusebenzisa le ndlela zithambile kwaye zithambile, ezihlanjululwayo emva kwenkqubo ye-extrusion.

Ukutya
Inkqubo ye-extrusion iqala ngokuba ne-rubber compound yondliwe kwi-extruder.

Screw esijikelezayo
Ikhompawundi yerabha ngokucothayo ishiya i-feeder kwaye ityiswa kwisikrufu esiyihambisa ukuya kwidayiti.

I-Rubber Tubing Die
Njengoko imathiriyeli yerabha ekrwada ishukunyiswa sisikrufu, inyanzeliswa ngokufa ngokomlinganiselo ochanekileyo wobubanzi kunye nobukhulu betyhubhu.Njengoko i-rubber isondela kwi-die, kukho ukwanda kweqondo lokushisa kunye noxinzelelo, obangela ukuba izinto ezikhuphayo zidumbe kuxhomekeke kuhlobo lwe-compound kunye nobunzima.

Vulcanization
Ekubeni irabha esetyenzisiweyo kwinkqubo yokukhupha i-extrusion ingavulwa, kufuneka iqhube uhlobo oluthile lwe-vulcanization xa sele idlulile kwi-extruder.Nangona unyango ngesulfure yayiyeyona ndlela yakuqala yokwenza ivulcanization, ezinye iintlobo ziye zaphuhliswa yimveliso yanamhlanje, ebandakanya unyango lwemicroware, iibhafu zetyuwa, okanye ezinye iindlela zokufudumeza.Inkqubo iyimfuneko yokunciphisa kunye nokuqina kwemveliso egqityiweyo.
I-vulcanization okanye inkqubo yokunyanga inokubonwa kulo mzobo ungezantsi.
