Isi yometseho ni iyishimishije, yuzuyemo ibikoresho byinshi, ibishushanyo, nibisabwa.Mubice byinshi bigize ifatizo zifatika, ibintu byibyimbye bigira uruhare runini.Izi mikorere zifite inshingano zo gutanga ibishishwa no gutuza kuri adhesif, kwemeza ko ikora neza mubihe bitandukanye kandi ikubahiriza neza insimburangingo zitandukanye.
Iriburiro ryibibyimba bifata neza:
Ibikoresho byibyimbye, bizwi kandi nka rheologiya ihindura cyangwa byongera ububobere, ni ibintu byongewe kumavuta kugirango byongere ubwiza cyangwa ubunini.Bakora imirimo myinshi ikomeye:
Igenzura rya Viscosity: Ibikoresho bibyibushye bigenzura ibiranga imigendekere yimitsi, kuborohereza kubishyira no kwirinda kugabanuka cyangwa kwiruka nyuma yo kubisaba.
Gutezimbere Adhesion: Mugukomeza kwijimye, ibintu byibyimbye birashobora kongera umubano hagati yumuti na substrate, kunoza imiterere ya adhesion.
Kwirinda Gutuza: Izi mfashanyo zifasha gukumira gutuza kwinshi no kwemeza gukwirakwiza ibice byose muburyo bwo gufatira hamwe, kuzamura umutekano no kubaho neza.
Gutezimbere Imikorere: Ibikoresho bifatanye akenshi byoroshye kubyitwaramo no kubikoresha mugihe cyo kubisaba, bitanga akazi keza kubakoresha.
Ubwoko bwibibyimba:
Ibikoresho byibyimbye bikoreshwa mubifata birashobora gushyirwa mubice byinshi ukurikije imiterere yimiti nuburyo bukoreshwa:
Polimeri:
Inkomoko ya selile: Ingero zirimo hydroxyethyl selulose (HEC), methyl selulose (MC), na carboxymethyl selulose (CMC).Izi polymers zishonga mumazi kandi zitanga ibintu byiza cyane.
Polimeri ya Acrylic: Ibibyimba bya Acrylic, nka polyacrylates, bitanga ibintu byinshi kandi bigahuza hamwe nuburyo butandukanye bwo gufatira hamwe.
Polyurethanes: Ibibyimbye bishingiye kuri polyurethane bitanga umusaruro mwinshi wo kubyimba no kugenzura imvugo mungingo zishingiye kumashanyarazi.
Inkoko zidasanzwe:
Ibumba: Ibumba risanzwe nka bentonite na montmorillonite rikoreshwa cyane nkibibyimbye mumazi ashingiye kumazi.Bakora mugukora imiterere y'urusobe rwongera ubwiza.
Silica: Silica yaguye hamwe na silika ya siloidal ikoreshwa nkibibyimbye muburyo bwo gufatira hamwe, cyane cyane mubikoresho bishingiye kuri silicone.
Inkoko kama:
Xanthan Gum: Ikomoka kuri fermentation ya mikorobe, ganthan gum nigikoresho cyiza cyane kibyibushye gikwiranye nubwoko butandukanye bwo gufatira hamwe.
Guar Gum: Ubundi umubyimba usanzwe, guar gum, ukomoka ku bishyimbo bya guar kandi ukoreshwa cyane cyane mumazi ashingiye kumazi.
Amashanyarazi: Ibinyamisogwe byahinduwe, nk'ibigori by'ibigori cyangwa ibirayi by'ibirayi, birashobora gukora nk'ibyimbye bikora neza.
Inkoko zifatanije:
Ibibyimbye bikora mugukora amashyirahamwe hamwe nizindi molekile muburyo bwo gufatira hamwe, gukora urusobe rwongera ububobere.Ingero zirimo polymers yahinduwe na hydrophobique (HMPs) hamwe na polyurethane yibyibushye hamwe nitsinda rifatanije.
Ibintu bigira uruhare mu guhitamo abakozi babyibushye:
Guhitamo uburyo bwiza bwo kubyibuha kugirango ubone ibintu bifatika bikubiyemo gusuzuma ibintu bitandukanye:
Ubwuzuzanye: Umubyimba ugomba guhuzwa nibindi bice bigize ifumbire mvaruganda, harimo ibishishwa, ibisigazwa, ninyongeramusaruro.
Gukemura: Ukurikije ubwoko bufatika (bushingiye kumazi, bushingiye kumashanyarazi, cyangwa gushonga), umubyimba ugomba kuba ushonga cyangwa ugatandukana muburyo bwatoranijwe cyangwa hagati.
Imiterere ya Rheologiya: Imyitwarire ya rheologiya yifuzwa yifata (shear thinning, thixotropic, nibindi) iyobora ihitamo ryibibyimba hamwe nibitekerezo byayo.
Uburyo bwo gusaba: Uburyo bwo gukoresha (gukaraba, gutera, nibindi) hamwe nubunini bwifuzwa bwifuzwa bigira ingaruka kumahitamo yibyimbye nibiranga ubwiza bwayo.
Ibitekerezo by’ibidukikije: Amabwiriza y’ibidukikije hamwe n’ibitekerezo bishobora kugabanya ikoreshwa ry’ibintu bimwe na bimwe byongera umubyimba, nk'ibimera kama bihindagurika (VOCs) mu gufatira ku musemburo.
Ahantu ho gusaba no gutekereza:
Umubyimba ushakisha porogaramu mu nganda zitandukanye n'ubwoko bufatika:
Ibikoresho byubaka: Ibikoresho byo kubyimba bikoreshwa mubikoresho byubaka kugirango bihuze ibikoresho nkibiti, ibyuma, beto, nubutaka.Baremeza neza icyuho cyuzuye no kuba inyangamugayo.
Ibikoresho byo gupakira: Mubikoresho byo gupakira, aho ibifunga bikoreshwa mugushiraho no guhuza amakarito, impapuro, na plastike, ibintu byibyimbye bitanga igenzura ryijimye kandi bikarinda gusohoka mugihe cyo kubisaba.
Ibikoresho bifata ibinyabiziga: Ibikoresho bifata ibinyabiziga bisaba kugenzura neza imiterere ya porogaramu nko guhuza umubiri, guteranya imbere, no gushiraho ikirahure.
Ibikoresho bifata ibiti: Ibiti bifata neza hamwe nibiti bifashisha mugukora ibiti byunguka ibintu kugirango bigere kumurongo ukomeye kandi birinde gutonyanga cyangwa kwiruka mugihe cyo kubisaba.
Ibikoresho byo kwa muganga: Mubikorwa byubuvuzi nko kwambara ibikomere, ibibyimba byanduye, hamwe n’ibikoresho byo kubaga, imiti igabanya ubukana itanga neza kandi ikabangikanya.
Ibikoresho byibyimbye nibintu byingenzi bigize ibice bifatika, bitanga igenzura ryijimye, ituze, hamwe nibikorwa byongerewe imbaraga muburyo butandukanye bwa porogaramu.Guhitamo kubyimbye bikwiye biterwa nibintu nko guhuza, gukemura, imiterere ya rheologiya, nibisabwa.Hamwe niterambere rihoraho mubikoresho bya siyansi nubuhanga bufatika, iterambere ryibintu byongera umubyimba byizeza kurushaho kunoza imikorere no guhuza ibimera mu nganda zitandukanye.Mugihe ifatizo zifatika zikomeje kugenda zihinduka kugirango zuzuze ibisabwa n’inganda zigezweho n’ubwubatsi, uruhare rw’ibibyimba bikomeza kuba ingenzi mu kwemeza intsinzi no kwizerwa by’ibisubizo bifatika.
