Ibiranga ubushobozi bwa Polyurethane / Ibirango vy'Igitsina

Inyuma y’imyaka myinshi y’iterambere, ubuhinga bwo gukura amapolyurethane bwaraguzwe. Mu gihe c’ugukwega kwa polyurethane no gufyonda, hashobora gukoreshwa intsinga zirushirije gukomera, kugira ngo inkomezi z’ico kintu zigwire cane. Muri ico gihe nyene, kubera inkomezi nziza cane, inkomezi z’ugukomera n’inkomezi z’ugukemura kw’ibintu vy’agaciro vy’ivyo bihimba vy’umubiri ubwavyo, ivyo bintu birashobora gukorwa bigoranye kandi bikaba vyoroshe.
Nk’akarorero, I-beam ishobora gukorwa n’ubudodo bw’umwimerere n’ubudodo bw’umwimerere n’ubudodo bw’umwimerere budakomeza, kandi bugagabanya uburemere bw’I-beam kuva kuri 3.3mm gushika kuri 2.6mm, mu gihe buguma bufise uburemere bwabwo bw’uburebure butahindutse. Ivyo bigabanya igicuruzwa ku rugero rwa 13% kandi bikaba bigura 7%. Ikindi, kubera ko ivyo bikoresho vy’ugusohora polyurethane ari bike cane, birashobora gukoranirizwa hamwe mu buryo busanzwe ataco bimenagurika kandi bikajanjagurwa.
Mu buryo bwihariye, gukoresha ubuhinga bwo gukuraho polyurethane kugira ngo umuntu ashobore gukuramwo polyurethane afise ivyiza bigaragara mu bintu bikurikira.(1) Gushika ku bice bine canke bitanu bitandukanye vy’ibara ry’ibirahuri bishobora gukenerwa. Ivyo bitegerezwa kuba bitegerezwa gutemwa kandi bikagira ishusho. Ukoresheje polyurethane gukwegakwega, kenshi irashobora gukoresha urudodo rw’ibirahuri rutagira igipfukisho aho gukoresha urudodo rw’ibirahuri. Ugukuraho urudodo rw’ibirahuri vyumvikana ko bigabanya igiciro c’ibikoresho vya mbere be n’igiciro c’abakozi co gukoresha ivyo. Ivyo bishobora gutuma imashini imeneka bitagoranye, kandi ibisigazwa birashobora guhagarika imashini, bikagira ico bikoze ku guhingura. Gukuraho ivyiyumviro birashobora kwongera umuvuduko wo gukora mu bihe vyinshi, gutyo bikaba bituma igiciro kigenda neza. Ku rundi ruhande, inyuma yo gusubiriza kwumva n’ugutera imbere bitagaragara, ibirimwo vy’insinga birashobora kwongerekana gushika ku 80%, mu gihe ibirimwo vy’insinga z’ibintu vyinshi bitagira - popolyurethane - ibintu vy’inyuma ni 60%. Muri ubwo buryo, ibirimwo vy’ibirahuri vyinshi bifatanijwe n’ubushobozi bwiza bwo gutuma habaho urutonde rw’ugusohora polyurethane n’inkomezi nziza n’ugukomera.(2) Ivy’inkomezi nyinshi vy’ugukwega kwa polyurethane - ibikoresho vy’inyuma bifungura ibikorwa bishasha. Ivyo bikoresho bishobora gukoreshwa mu ntumbero zitagira ubushobozi bw’ivyuma vy’ivyuma vy’ivyuma mu kibanza c’ivyuma n’ivyuma vy’aluminium mu masoko y’ubwubatsi, ibikorwa remezo n’ivy’ugutwara abantu. Umutwe w’urupfu w’intango, igikoresho co gushusha n’igikoresho gishobora gukoreshwa.(4) Uretse imiterere y’umubiri iri hejuru n’ivyiza vyo gukora, ibihimba vy’ugukwega kwa polyurethane n’ugusohoka na vyo nyene birafise akamaro ko gukoraniriza hamwe, cane cane ukuntu umuntu afatanya. Kubera inkomezi za polyurethane, nta nkenerwa yo gutera imbere y’igihe iyo ushizeko igikoresho ku gikoresho ca polyurethane, ivyo bikaba bishobora kuzigama umwanya n’ibikorwa. In turn, the force required to pull the screw in the polyurethane product is more than twice the force required to pull the screw.(5) Under the same fiber structure, all the properties of polyurethane / glass fiber pull-extrusion products are better than those of ordinary thermosetting resin, with close bending modulus, impact strength greatly improved, high drawing strength of screw, good opening crack resistance, excellent wear resistance, good secondary processing ability, heat resistance y’ibipimo birenga 240. Igihimba nyamukuru c’ivyuma vy’ivyuma vy’ivyuma (6) polyurethane / y’ibirahuri ni co gikoresho ciza kuruta ibindi vyose, igice c’ibikoresho, umuvuduko w’amazi, amazi, aside, alkali, umunyu ni bwo bwiza kuruta ubundi bwose, bwo gupfuka, gutera imbere, gutera imbere mu mubiri, nta n’ikintu gitera ububabare, nta n’ikintu gikingira umubiri, kibungabunga ibidukikije.
