Ibisobanuro by'igicuruzwa

Porogaramu ya Viscose shellac

Ubwa mbere, ikoreshwa mu gukora umukandara w’inyenzi ufatana, icyuma gifatana cy’inyundo, nibindi. Shellac zitandukanye zishobora gukoreshwa mu gukora kaseti ifatana, icyuma gifatana, icyuma gifatana cy’inyenzi, icyuma gifatana cy’inyenzi, nibindi. Ikibazo nyamukuru ni uko: ibicuruzwa bitandukanye bigomba gukoresha shellac ya viscose itandukanye, ntabwo ishobora kuba rusange. Uburyo bwo gukora ibi bicuruzwa mu nganda bwamaze gukura kandi bukora urunigi rwuzuye rw’inganda.
Icya kabiri, gushyiramo umubyimba mu buryo butaziguye. Ikibazo gikunze kugaragara mu gushyiramo shellac ku giti ni uko bigoye cyane kuyishyiramo. Kugira ngo iki kibazo gikemuke, abakora ibikoresho bitandukanye bagerageje uburyo butandukanye, kandi nta gisubizo gihendutse cyabonetse mu myaka myinshi. Igisubizo gisanzwe ni uguhindura formula ya viscose shellac kugira ngo ihinduke ubushyuhe. Ariko, imikorere y'umuti iragabanuka cyane, kandi ntushobora no kwitwa viscose shellac.” “Injectable shellac” ikemura ibibazo byavuzwe haruguru.
Icya gatatu, dukurikije imiterere itandukanye y’udukoko dutandukanye, dukozwe mu mabara atandukanye kugira ngo dukure udukoko. Agashishwa k’umuhondo gashyirwa ku kibaho cy’umweru gikoreshwa mu gukora ikibaho cy’umuhondo, naho agashishwa k’ubururu gashyirwa ku kibaho cy’umweru gikoreshwa mu kwica udukoko nka thrips. Agashishwa k’umweru wa viscose gashyirwa ku kibaho cy’umweru gikoreshwa mu gukora ikibaho cy’umweru gikoreshwa mu gukora ikibaho cy’umweru cya armyworm, gikoreshwa mu kwica udukoko nka diamond-moth.

Ishyirwa mu byiciro rya Viscose shellac

Viscose shellac Dukurikije ahantu hatandukanye hakoreshwa, viscose shellac ishobora kugabanywamo ubwoko bubiri bukurikira:
(1) Igishishwa cyo mu nzu gifatana gikwiriye gukoreshwa mu buzima, nka: kole ifatana, kole y'inkoko, nibindi. Kirangwa no gufatana guke ugereranyije n'ubwoko bw'umurima, ikoranabuhanga ryoroshye ryo gukora no gushushanya ibintu byoroshye.
(2) Kole zo mu bwoko bwa field zikoreshwa mu buryo karemano mu kwica udukoko, nka: haha ​​kole, gun adhesive shellac, injection adhesive shellac. Ibiranga ni: gufata neza, kurwanya gusaza, gukora ibintu bigoye, ibisabwa mu buryo buhanitse.

(1) Ibikoresho byo mu bwoko bw'ibicuruzwa bikingira ibidukikije bishobora kwangirika bitewe n'umuvuduko ushyushye kandi bihenze cyane, biragoye kubitegura.
(2) Ibikoresho gakondo byo mu bwoko bwa rosine bishobora kwibasirwa n'umuvuduko wa rosine bikoreshwa cyane cyane mu gutegura shellac ya viscose yo mu nzu. Inganda nyinshi zikora mu ngo zikoresha ubwo bwoko bwa shellac ifata. (3) Ubundi bwoko bwa shellac ya viscose bushobora kwibasirwa n'umuvuduko ntibungana mu byiza no mu bibi, kandi biragoye gutandukanya ukuri n'ikinyoma.

(2) Kole y'umuhondo woroshye, igice kinini cy'ubu bwoko bwa kole ni kole ya rosin, igice gito ni uruvange rwa polybutene rwo hasi, kandi bamwe bakoresha polypropylene, polybutene ivanze muri viscose shellac.
(3) Kole y'umukara, ubwo bwoko bwa kole ni kole ifata umuvuduko nk'uwa rubber, ifite impumuro mbi kandi ikoreshwa cyane cyane mu gusana imbeba.

Uburyo bwo gukuraho:

1. Iyo ishyizwemo kole gusa, ishobora kwinjizwa mu mazi ashyushye hanyuma igasukurwa n'isabune yo gusangiriraho amasahani.
2. Niba kole yafatiriwe ku biganza, ushobora gukoresha amavuta yo guteka kugira ngo woze kandi woroshye, usukure kole, hanyuma woze amavuta ku biganza n'isabune.
3. Ushobora kandi gukaraba divayi yera, hanyuma ukayishyira mu mazi ashyushye kugira ngo ukureho kole. Amakuru maremare Ubwoko bw'impapuro zifata isazi. Iyo zikoreshejwe, impapuro zifata isazi zishyirwa ku nkengero z'impapuro n'intoki, zigashyirwa ahantu isazi zikunze kugurukira cyangwa zicucitse, igihe cyose isazi ikoze cyangwa igwa ku mpapuro, izafata neza. Iyo zimanitswe hafi y'urumuri, zishobora no gufata imibu n'utundi dukoko tuguruka. Gutegura impapuro za kaseti: Shyira umweru w'ikinyobwa mu gikoresho, ongeramo 1/3 cy'amazi muri formula, kugira ngo ishonge neza, hanyuma ukate impapuro za kraft mo uduce, ongeramo kole ku mpapuro za a na B kraft, wumishe. Kora kole y'ibisazi: shyira rosin mu nkono ya porcelain, ongeramo 2/3 by'amazi asigaye, shyushya, tegereza rosin ishonge, hanyuma ushyushye amazi ashyushye, iyo amazi ari mu nkono yumye vuba, ongeramo vuba amavuta ya paulowne n'amavuta ya castor, uvange neza, hanyuma wongere ubuki ku buryo bungana, komeza gushyushya amazi arenze.
