Uduce duto mu gukora no gutunganya kole ikoze mu buryo bwa hotmelt dushobora guhindura cyane imiterere y’ukole ikozwe mu buryo bwa adhesion. Kugenzura ubukana buhoraho ni ingamba y'ingenzi yo kuzamuraumurongo wo gukora kole ishyushyeimikorere myiza. Reba uburyo bwo guhuza ibintu mu buryo bw'igihe nyacyoigikoresho cyo gupima ubuninikurinda ibintu bihindagurika no gufungura amahirwe yo kugabanya ikiguzi no kunoza uburyo burambye.
Incamake y'Isoko rya Hot Melt Adhesive
Urwego rw’ubukorikori bushyushye burimo kwaguka cyane ku nganda zirushaho gushyira imbere ibisubizo byihuse kandi bigamije ibidukikije, aho icyerekezo kigaragaza iterambere rirambye riterwa n’udushya mu bijyanye no gupakira no gupakira imodoka.
Amakuru aherutse kugaragaza ko isoko mpuzamahanga rifite agaciro ka miliyari 9.08 z'amadolari y'Amerika mu 2024, ryiteguye kwaguka ku gipimo cy'izamuka ry'ubukungu ku mwaka (CAGR) cya 4.3% kugeza mu 2030, rikagera kuri miliyari 11.8 z'amadolari y'Amerika, bitewe n'ubwiyongere bw'abashaka ibikoresho bidafite ibinyabutabire bigabanya ingaruka ku bidukikije. Iyi nzira yubakiye ku byari byateganyijwe mbere, nko kuzamuka kwa CAGR ya 5.5% kuva mu 2021 kugeza mu 2028, ariko uko ibintu bimeze ubu bigaragaza ukwiyongera muri Aziya na Pasifika, ifite imigabane irenga 40% bitewe n'inganda zikoresha ibikoresho nk'ubwubatsi n'imyenda.
Muri ibi, kole zikozwe mu buryo bushyushye bwo gushonga (HMA) zigaragaza ahantu hanini, hateganijwe ko zizakura hamwe bitewe n’uburyo zikoresha mu gushushanya no mu tuntu duto, aho abahanga mu bya tepi nka 3M, Henkel, na HB Fuller bibanda cyane ku miti ikomoka ku binyabuzima kugira ngo ihuze n’ibipimo by’amategeko.
Igikoresho cyo gufunga gishyushye (Hot Melt Adhesive) ni iki?
Tekereza kole ihinduka kuva ku ishusho ikomeye ku bushyuhe bwo mu kirere ikajya ku mazi ashyushye, igakora imikoranire ikomeye uko ikonje—ibi bikubiyemo kole zishyushye zishonga (HMAs), zizwiho imiterere yazo ya thermoplastic ivanga polymer, resins, waxes, n'ibindi bikoresho bikavamo ingufu zidafite solvent.
Mu by’ukuri, HMA zigaragara neza mu bihe bisaba guteranya vuba, nk’ibicuruzwa by’isuku cyangwa ibikoresho by’ikoranabuhanga, aho ubushobozi bwabyo bwo kuziba icyuho no kugabanuka guke bitanga uburyo bwo gufatana neza ku bikoresho nka pulasitiki, ibyuma, n’imyenda. Gufatana kw’ibipimo by’umuvuduko bikomeza kuba nk’aho ari ibintu bito nyuma yo gukoresha, bigatuma imigozi ishobora gusubizwa ku makaseti n’ibirango; ibi akenshi bikoresha copolymers za styrenic block kugira ngo zirusheho gukomera no gukomera, bitanga ibyiza nko gushyiraho vuba nta ntambwe zihinduka.
Kuba nta bintu bihumanya ibidukikije (VOCs) bikomeza gusa kubahiriza ibidukikije, ahubwo binatuma byoroha kwihuza n’ibintu byikorasisitemu zo gutanga kole ishyushye, bituma HMA ziba inkingi ikomeye mu nganda zigezweho aho umuvuduko n'uburambe bihurira.

Uburyo bwo gukora Hotmelt Adhesive
Gutunganyaumurongo wo gukora kole ishyushyebisaba uburyo bukurikiranye bushyira imbere ubumwe n'ubuziranenge, cyane cyane kuriHMNk'aho copolymers za block zikenera kuvanga neza kugira ngo zigere ku gufunga no guhuza neza. Ukurikije protocole nziza nakoresheje, inzira irimo uburyo bwo kugaburira no kuyungurura bugezweho kugira ngo yuzuze uburyo bwo kugenzura ubushyuhe:
● Guhitamo ibikoresho fatizo: Gutunganya ibikoresho byo gufunga, gusiga irangi, n'ibindi bikoresho byongera ubuziranenge bwa polymer, ugenzura ibipimo kugira ngo wirinde ihindagurika rya viscosity.
● Kuvanga no gupima mbere y'uko bivangwa: Gupima neza ibintu, akenshi mu bipimo byikora, kugira ngo bibe imvange y'ibanze yiteguye gushonga.
● Gushonga no Kuvanga: Gushyushya muri reactors kugeza kuri 150-200°C, hakoreshejwe agitators kugira ngo hakwirakwizwe kimwe mu gihe hakurikiranwa impinduka hagati ya molekile kugira ngo habeho urujya n'uruza rwiza.
● Guhuza no Gukuraho Imyuka: Koresha sisitemu zo gukuramo umwuka n'ibintu bihumanya, ni ingenzi cyane kugira ngo hatabaho ibibyimbaHMAzikomeza ubunyangamugayo.
● Kuyungurura: Unyuza mu byuma byihariye (urushundura, karito, umufuka) kugira ngo ukureho imyanda, ishyizwe mu buryo bw'ingenzi kugira ngo ishonge neza.
● Gukoresha irangi cyangwa Slot Die: Kuramo cyangwa usuke mu bimera, ugenzura uko amazi agenda ku buryo nyabwo nk'imisego cyangwa ibiti.
● Gukonjesha no Gukomera: Koresha imashini zikonjesha n'izikoresha ubushyuhe bw'ibimera kugira ngo bikomere vuba, ibihe bitandukanye bitewe n'ingano kugira ngo wirinde ibitagenda neza.
● Gupfunyika: Shyira mu bikoresho bibungabunga ibidukikije, urebe ko amazi adashobora kugwa mu bubiko kugira ngo bigumane ubushyuhe.
● Igenzura ry'Ubuziranenge: Ikizamini cyaHMA-ibintu byihariye nko gukomera kw'igishishwa no kudafata neza, hamwe n'ibipimo bisanzwe.
Uku kwiyongera k'urujya n'uruza rw'amazi, hamweHMAIntambwe zishyirwa hagati nko gusiga ifu y'ibimera mbere yo kubishyiraho kugira ngo byoroshye kubisohora, byongera imikorere iyo bihujwe no kugenzura ibintu mu murongo.
Ibipimo by'ingenzi byo gukurikirana ibikorwa
Gukurikirana ibintu by'ingenzi mu buryo bwitondewe muri rusangeIkorwa rya HMAikomeza kurwanya ibitagenda neza bishobora kwangiza imikorere ya kole, no muriHMAmu bihe bitandukanye, ibipimo nko kugumana tack mu gihe cy'umuvuduko birushaho kuba ingenzi cyane kugira ngo ikoreshwa ry'inyongera ribe ryizewe. Hashingiwe kuri sisitemu zihujwe nashyizeho:
●Ubucucike: Igipimo cy'ibanze cyo kwirinda amazi, gikurikiranwa ku murongo kugira ngo gikomeze kuba hagati ya 500-50.000 cP, bigira ingaruka kuHMAUburyo bworoshye bwo gushyiramo no gukoresha neza.
●Ubushyuhe: Guverinoma zishonga (kugeza kuri 200°C) kandi zigatunganya imyuka, hamwe n'uburyo bwo kugenzura neza budatuma yangirika.
● Igitutu: Igenzura urwego rwa reactor/ubwato (kugeza kuri 1.6 MPa) no gukoresha vacuum kugira ngo ikuremo imyuka, birinda kuziba.
● Umuvuduko wo Kuvanga/Gukata: Iringaniza uburinganire nta gukata ibice by'ingenzi muHMA.
● Aho koroshya:HMA-byihariye, 60-150°C, bitegeka ubushyuhe.
●Igihe cyo gufungura n'igihe cyo gushyiraho: KuriHMAs, bitanga ubushobozi bwo kongera gushyira ibintu mu mwanya wabyo (amasegonda 5-30) no guhuza ibintu byihuse.
●Ihindagurika ry'Ubuzima mu Nkono: Ikurikirana uburyo bwo gushonga buramba, ikongera imbaraga mu kurwanya ibiyobyabwenge.
● Igipimo cy'amazi n'urwego rw'umwanda: Binyuze mu byuma bitanga ibiribwa n'ibiyungurura, bikomeza ubuziranenge >99%.
