Guhingura amapulasitike ni ubuhinga bw’ubuhinga bujanye n’uburyo butandukanye bwo guhindura amapulasitike ngo abe ibintu vy’amapulasitike. Mu gihe c’iryo hinduka, kimwe canke vyinshi muri ibi bikurikira birakunda kubaho: ihinduka mu bijanye n’uguhinduka kw’ibihimba vy’umubiri n’imiterere y’ibintu vy’umubiri n’ivy’imiti.
Gubumbabumba
Ibikoresho nyamukuru vyo gubumbabumba mu buryo bw’ugufatanya ni igikoresho co gucapura n’igikoresho co gubumbabumba. Igikoresho gikoreshwa cane ni igikoresho gikoreshwa n’amazi, kikaba gishobora gutwara amatoni kuva ku mirongo gushika ku majana. Hariho ibikoresho vyo hasi-vy’umuvuduko n’ibikoresho vyo hejuru-vy’umuvuduko. Igikoresho gikoreshwa mu gukora ibikoresho vy’ugufatanya citwa igikoresho co gufatanya, kikaba kigizwe n’ibice bitatu: ibikoresho vy’ugusesa amaraso, ibikoresho vy’ugusesa amaraso bimwe bimwe, n’ibikoresho vy’ugutera ivyuma vy’ugusesa amaraso. Inyungu nyamukuru z’ugubumbabumba mu buryo bw’ugufatanya ni uko bishobora gubumbabumba ibintu bifise ibibanza bininibinini bigororotse kandi bishobora guhingura ibintu vyinshi. Inyungu zayo ni inzinguzingu ndende zo gukora n’ubushobozi buke.
Gubumbabumba urushinge
Gubumbabumba mu bipande bikunda gukoresha igikoresho co gubumbabumba. Ubwo bwoko bw’ivyuma bikoreshwa mu gucapura burafise amasahani menshi areremba ashushe hagati y’amasahani y’ivyuma agendagenda n’ayahagaze. Ibikoresho bikoreshwa cane mu gukomeza mu guhingura ibintu bifise amabara ni nk’impuzu y’ipampa, impuzu y’ibirahuri, impapuro n’impuzu y’amabuye y’agaciro. Ivyo bikoresho birimwo ivyuma bita phenolic, ivyuma bita epoxy, ivyuma bita polyester bitagira amazi, be n’ivyuma bimwebimwe bikoreshwa n’ubushuhe. Injection gufuha ububumbano, extrusion gufuha ububumbano, gukuraho gufuha ububumbano, gupfuka filime, gupfuka ivyuma bishushe, gutera igitanda gifise amazi, gutera urubeya, gutera umuyagankuba, gutera plasma.

Guhingura ibintu biva hanze, bizwi kandi nk’uguhingura ibintu biva hanze canke guhingura ibintu biva hanze, ni uburyo bwo guhingura ibintu bihoraho biciye ku gipfunsi kiri mu gihe c’ugutemba biciye mu kubishushanya no kubitera umukazo mu gikoresho co guhingura ibintu. Ivyo gusohora bikoreshwa cane cane mu guhingura ibintu bifise ubushuhe, ariko kandi birashobora gukoreshwa mu bikoresho bimwebimwe bishobora gukomera. Ibintu biva hanze ni ibintu bikomeza, nk’imiyoboro, inkoni, intsinga, amafilime, n’ivyuma vy’intsinga n’ivy’intsinga. Vyongeye, irashobora gukoreshwa mu guvanga amapulasitike, mu guhindura amapulasitike, mu gutera amabara no mu kuyavanga. Imashini yo guhingura ibintu biva mu nzu igizwe n’ibikoresho vyo gusohora ibikoresho, uburyo bwo gutanga amakuru, n’uburyo bwo gushusha no gukonjesha. Ivyo bikoresho biva mu bwoko bubiri: ubwoko bw’ivyuma (ivyuma bimwe n’ivyuma vyinshi-) n’ubwoko bw’ivyuma. Ica mbere ni igikorwa co gusohora gikomeza, mu gihe ica kabiri gica gihagarara. Igishushanyo c’ishimikiro c’igikoresho kimwe-gikoreshwa n’ivyuma ahanini gifise igikoresho co gutanga amakuru, igikoresho co kugaburira, umugozi, ivyuma, umutwe w’urupfu, n’urupfu. Ibikoresho vy’inyongera vy’ibikoresho vy’ugusohora biva mu mice itatu nyamukuru: ibikoresho vyo gutegura ibikoresho imbere y’igihe (nk’ugutwara ibikoresho no kuvyuma), ibikoresho vyo gutunganya ibikoresho (guhingura, gukonjesha, gukurura, gukata canke gutera), n’ibikoresho vyo kugenzura uko ibintu bimeze.
Gubumbabumba
Pultrusion ni bumwe mu buryo bwo guhingura amapulasitike akomeye y’insinga-ashobora gukomera. Ikoreshwa mu guhingura imirongo ifise umusaraba-umubumbe udahinduka n'uburebure butagira aho bugarukira. Ivyo bikoresho bikoreshwa mu kubumbabumba birimwo gukura intsinga zikomeza zishizwemwo ivyuma biciye mu gipfukisho gishushe, hanyuma zigakomeza gukiza ivyuma mu cumba co gushushanya kugira ngo haboneke igikoresho c’ipulasitike gikomeza gukomera cane gifise inzira imwe.
Ivyo bikoresho bikoreshwa cane mu guhingura ibintu bikoresheje ubuhinga bwa pultrusion harimwo polyester idafise amazi, epoxy na silicone. Igikoresho citwa polyester kitagira amazi ni co gikoreshwa cane. Igikoresho co guhingura ibintu bikoresheje ubuhinga bwa pultrusion mu bisanzwe gifise igikoresho co gutunganya intsinga, itangi ry’ivyuma, igikoresho co gutegura, igikoresho co gupfa no gushusha, igikoresho co gukurura, n’ibikoresho vyo gukata.
