Uburyo bwo gukora impuzu za PVC
Impuzu y’ibara ry’agahama (Polyvinyl Chloride Stretch Fabric) ni igikoresho gishobora guhinduka gikozwe ahanini mu gitambaro c’ibara ry’agahama (PVC) biciye mu buryo bwihariye. Ikoreshwa cane mu bikorwa nk’amahema, ibitambaro vyo kwamamaza, amakoti y’imvura, n’ibikingi. Ivyo bihimba vy’umubiri birimwo intambwe nyinshi z’ingenzi, harimwo no gupima ibikoresho vya mbere, kubivanga, kubigira nk’ipulasitike, kubirambura, no kubikora inyuma y’-. Gucungera neza ibipimo vy’imigenderanire birakenewe kugira ngo igicuruzwa giheza gikore neza.
Ibikoresho bitagira agaciro n'Ivyateguwe
Igikoresho nyamukuru c’impuzu za PVC ni polyvinyl chloride resin, mu bisanzwe PVC ihagaze canke ipfutse ifise uburemere buringaniye n’ubushuhe bwiza. Kugira ngo ishobore guhinduka, guhangana n’ibihe, n’ubushobozi bwo gutunganya, harimwo ibintu bitandukanye vyongerwako, harimwo ibintu bitera amapulasitike (nk’ibintu bita phthalates), ibintu bituma ibintu biguma bimeze neza (nk’ibintu bitera amavuta bikomeye vy’ivyuma bita calcium-zinc complex), ibintu bitera amavuta (nk’aside stearic), ibintu bitera amavuta (nk’ibintu bitera amavuta bita calcium carboniz). Ivyo bintu vy’inyongera bitegerezwa kuvangwa neza n’ivyuma vya PVC mu bipimo vyihariye kugira ngo bibe bimwe bimwe.
Kuvanga no guhindura ivyuma
Ivyo guvanga ibikoresho vya mbere ni intambwe ihambaye mu gukora impuzu zitambagira za PVC. Ica mbere, ivyuma vya PVC n’ibindi bintu bitandukanye bishirwa mu gikoresho co guvanga gifise umuvuduko munini-hakurikijwe igipimo categuwe. Ivyo bivanze bivyurwa ku bushuhe bwa 80-120 degrees mu minota 10-20 kugira ngo igikoresho co gutera ivyatsi gishobore kwinjira neza mu bihimba vya PVC maze kibe ikivange c’umye kimwe. Ivyo bivanze vyumye bica binjira mu gikoresho co mu mutima canke mu gikoresho co gusohora amahasa kugira ngo bibe plastique. Ubushuhe n’ugukemurwa bituma PVC ihinduka ikintu kimwe. Ubushuhe bwo guhindura ivyuma bugenzurwa hagati ya degre 160-190 . Ubushuhe bwinshi cane burashobora gutuma PVC ibora, mu gihe ubushuhe buke cane bushobora gutuma amazi agenda neza.
Gukaraba
Ivyo bikoresho vy’impuzu vy’i PVC bishobora guhindurwa igitambaro c’ishimikiro hakoreshejwe ubuhinga bwa calendering canke ubuhinga bwo gufuha. Gukora ikalendari birimwo gukanda iyo nkoko biciye mu kalendari y’imizingo myinshi mu gipande gitoya, hanyuma kigashirwa ku kintu c’ishimikiro (nk’igitambaro giboshe canke kitaboshe) hanyuma kigakonja kugira ngo kibe igitambaro gikozwe mu bipande vyinshi. Gukaraba ni intambwe nyamukuru mu kwongerera ubushobozi bwo guhinduranya no gukomera kw’impuzu yo kurambura ya PVC. Impuzu y’ishimikiro iramburwa cane cane mu burebure canke mu buryo bujanye n’ubushuhe (80-120℃), kenshi na kenshi incuro 2-3. Ivyo bintu bimaze kurambura, biraca mu nzira yo gutuma bigira ubushuhe kugira ngo bimeze neza aho uruzitiro rw’ibihimba vy’umubiri ruri, kandi ntibicike intege.
Post-Gutunganya no gutuma ibikorwa bigenda neza
Impuzu ya PVC iraheza irakonja, igazunguruka, igasukurwa ku ruhande (nk’ugupfuka n’ikintu kirekura canke gucapura). Kugira ngo ibintu bimwebimwe bishobore guhangana n’ibihe, birashirwako ibintu nk’ivyo bita acrylic canke polyurethane. Ikindi kandi, ugupima uburyo bukomeye (nk’ugupima ubushobozi bwo gukomera, ugukomera kw’amarira, n’ugupima ubushobozi bwo guhangana n’ubushuhe) biratuma igikoresho gihuye n’ingingo mfatirwako zo gukoresha.
Uburyo bwo gukoranya igitambaro ca PVC burashika ku kintu gikora cane -gihuza uguhinduka, ukudashobora guterwa n’amazi, n’ugukomera mu kugenzura neza igipimo c’ibikoresho vya mbere, ubushuhe bwo gutunganya, n’ibikorwa vy’ubuhinga, amaherezo bikaba bihuye n’ivyo inganda zikeneye zitandukanye.
