Indlela yokucubungula i-epoxy resin ibe yi-epoxy glass fiber tube

Inqubo yokukhiqiza ye-epoxy glass fiber tube iyinkimbinkimbi. Ungayenza kanjani i-epoxy resin ibe yi-epoxy glass fiber tube? Laba bakhiqizi abalandelayo be-epoxy glass fiber tube bazokwethula:

Izinto ezingavuthiwe zokwenza ishubhu ye-epoxy glass fibre iyi-monotonous adhesive-attached substrate njengento esetshenziswayo kanye ne-adhesive-attached esetshenziswa ngesikhathi esifanayo.

Ikakhulukazi indwangu yengilazi engenalutho nephepha elifakwe inhlaka ye-phenolic noma i-phenolic epoxy resin, indwangu kakotini efakwe inhlaka efanayo ingasetshenziswa endaweni eyodwa kuphela.

Ngesikhathi sokuvunguza, izinto ezinamathelayo zidlula i-tension roller kanye ne-guide roller bese ingena ku-roller yokusekela yangaphambili eshisayo. Ngemva kokushisisa futhi iba namathela, iyalinyazwa kumongo weshubhu esongwe ngefilimu. I-tension roller isebenzisa ukushuba okuthile kokunamathela kwesilonda. Ngakolunye uhlangothi, ukugoqa kuqinile, futhi ngakolunye uhlangothi, i-tube core ingagoqa ngosizo lokungqubuzana. Ukushisa kwe-roller yokusekela yangaphambili kufanele kulawulwe ngokuqinile. Uma izinga lokushisa liphezulu kakhulu, i-resin izogeleza kalula, futhi lapho izinga lokushisa liphansi kakhulu, ukunamathela okuhle kakhulu akunakuqinisekiswa.

Uma usebenzisa indlela yokusonta ukuze ulolonge ipayipi, qala ngokufaka i-ejenti yokukhulula kumongo wepayipi. I-ejenti yokukhulula ingenziwa nge-petroleum jelly, i-asphalt ne-wax emhlophe ngesilinganiso esikhulu se-1.5: 1: 1 ngemuva kokuxutshwa nokupholiswa. Uma usebenzisa, sebenzisa i-turpentine ukuze uyihlambulule ibe unama. I-tube core ehlanganiswe ne-ejenti yokukhulula kufanele imbozwe ngesigaba sezinto zokunamathisela njenge-backsheet, bese ifakwa phakathi kwama-shafts amabili asekelayo futhi i-pressure roller ibekwe phansi ukuze icindezele i-tube core.

Qondisa inxeba lezinto ezinamathelayo emshinini wokusonta ukuze udlulele komunye umkhawulo wefilimu, bese uwuvunguza kancane, futhi isivinini singandiswa ngemva kokujwayelekile.

Ingalawulwa ku-80-120 ℃ lapho isonga ishubhu le-phenolic. Uma ilimele ukushuba okuvamile, itheyiphu iyavinjwa, futhi ishubhu eligoqiwe elingenalutho kanye ne-tube core kukhishwa emshinini wokubopha amashubhu futhi ithunyelwe kuhhavini ukuze ilashwe. Lapho kukhiqizwa ishubhu ehlanganisiwe ye-phenolic, uma ukujiya kodonga kungaphansi kuka-6mm, kungafakwa kuhhavini ku-80-100 ℃, bese kushisiswe ku-170 ℃ ukuze kuphulukiswe amahora angu-2. Ngemuva kokuthi ukuqina kuqediwe, yikhiphe kuhhavini, uyipholise ngokwemvelo ekamelweni lokushisa, futhi ekugcineni ukhiphe ipayipi emgodini wepayipi.
