Kugwiritsa ntchito kwa viscose shellac

Choyamba, amagwiritsidwa ntchito popanga lamba womata wa ntchentche, mbale yomata ya nyongolotsi, ndi zina zotero. Shellac yomatira yosiyanasiyana ingagwiritsidwe ntchito kupanga tepi yomatira, bolodi lomatira, bolodi lomatira la ntchentche, nyumba ya cockroach, ndi zina zotero. Chinsinsi cha vutoli ndichakuti: zinthu zosiyanasiyana ziyenera kugwiritsa ntchito shellac yosiyana ya viscose, sizingakhale zapadziko lonse. Njira yopangira zinthuzi m'mafakitale yakula ndikupanga unyolo wathunthu wa mafakitale.
Chachiwiri, ikani thunthu mwachindunji. Vuto lofala kwambiri ndi kugwiritsa ntchito shellac mwachindunji pamitengo ya mitengo ndilakuti ndizovuta kwambiri kuyika. Pofuna kuthetsa vutoli, opanga osiyanasiyana ayesa njira zosiyanasiyana, ndipo pakhala palibe njira yotsika mtengo kwa zaka zambiri. Yankho lofala kwambiri ndikusintha njira ya viscose shellac kuti isungunuke. Komabe, magwiridwe antchito a mankhwalawa amachepa kwambiri, ndipo sangatchulidwe kuti viscose shellac. "Injectable shellac" imathetsa mavuto omwe ali pamwambapa.
Chachitatu, malinga ndi ma phototaxis osiyanasiyana a tizilombo tosiyanasiyana, opangidwa ndi mitundu yosiyanasiyana kuti akope tizilombo. Chipolopolo chomata chachikasu chimayikidwa pa bolodi loyera lonyamula kuti apange bolodi lachikasu, ndipo chipolopolo chabuluu chimayikidwa pa bolodi loyera lonyamula kuti apange bolodi labuluu, lomwe limagwiritsidwa ntchito kuwononga tizilombo monga thrips. Chipolopolo choyera cha viscose chofanana ndi mkaka chimayikidwa pa bolodi loyera lonyamula, lomwe limagwiritsidwa ntchito kupanga bolodi loyera la asilikali, lomwe limagwiritsidwa ntchito kuwononga tizilombo monga diamond-moth.

Kugawa kwa Viscose shellac

Malinga ndi malo osiyanasiyana ogwiritsira ntchito, shellac ya viscose ikhoza kugawidwa m'magulu awiri otsatirawa:
(1) Chipolopolo chomata chamkati choyenera kugwiritsidwa ntchito m'malo okhala, monga: guluu womata wa ntchentche, guluu wa cockroach, ndi zina zotero. Chimadziwika ndi kuuma kochepa poyerekeza ndi mtundu wamunda, ukadaulo wosavuta wopanga komanso kapangidwe kosinthasintha.
(2) Magulu a mtundu wa munda omwe amagwiritsidwa ntchito m'chilengedwe powononga tizilombo, monga: guluu wa haha, guluu wa mfuti, guluu wa jekeseni. Makhalidwe ake ndi awa: kumatira mwamphamvu, kuletsa kukalamba, njira yovuta yopangira, komanso kulondola kwambiri.

Malinga ndi mitundu yosiyanasiyana, imagawidwa m'magulu otsatirawa:

(1) Zinthu zoteteza chilengedwe zomwe zimakhudzidwa ndi kutentha kwa sungunuka kwa mtundu uwu ndi zovuta kuzikonza ndipo zimakhala zokwera mtengo.
(2) Zinthu zachikhalidwe zomwe zimakhudzidwa ndi kupanikizika kwa rosin zamtunduwu zimagwiritsidwa ntchito kwambiri popanga shellac ya viscose yamkati. Makampani ambiri opanga zinthu m'nyumba amagwiritsa ntchito mtundu uwu wa shellac yomatira. (3) Mitundu ina ya shellac ya viscose yomwe imakhudzidwa ndi kupanikizika ndi yofanana pakati pa chabwino ndi choipa, ndipo n'kovuta kusiyanitsa pakati pa zoona ndi zabodza.

Malinga ndi mawonekedwe a shellac yomatira, ikhoza kugawidwa m'magulu:

(1) Guluu wopanda utoto kapena woyera ngati mkaka, mtundu uwu wa guluu uli ndi khalidwe labwino kwambiri. Ndi wochezeka komanso woyenera kugwiritsidwa ntchito kumunda.
(2) Guluu wachikasu wopepuka, gawo lalikulu la guluu wamtunduwu ndi guluu wa rosin, gawo laling'ono ndi losakaniza la polybutene lotsika, ndipo ena amagwiritsa ntchito polypropylene, polybutene yosakanikirana ndi viscose shellac.
(3) Guluu wakuda, mtundu uwu wa guluu ndi guluu wogwirizana ndi kuthamanga kwa mpweya wa rabara, womwe uli ndi fungo loipa ndipo umagwiritsidwa ntchito kwambiri pokonza makoswe.

Njira yochotsera:

1. Ikangomatidwa, imatha kunyowa m'madzi ofunda kenako nkutsukidwa ndi sopo wothira mbale.
2. Ngati guluu wagwira m'manja, mungagwiritse ntchito mafuta ophikira kuyeretsa ndi kufewetsa, kuyeretsa guluu, kenako kutsuka mafutawo m'manja ndi sopo.
3. Muthanso kutsuka ndi vinyo woyera, kenako n’kuviika m’madzi ofunda kuti muchotse guluu. Chidziwitso Chowonjezera Mtundu wa pepala lomatira lomwe limagwiritsidwa ntchito kugwira ntchentche. Likagwiritsidwa ntchito, pepala lomatira lopangidwalo limachotsedwa m’mphepete mwa pepalalo ndi dzanja, ndikuyikidwa pamalo omwe ntchentche nthawi zambiri zimauluka kapena zokhuthala, bola ngati ntchentcheyo ikakhudza kapena kugwa papepalalo, lidzamatirira mwamphamvu. Ngati litapachikidwa pafupi ndi kuwala, limathanso kumamatira udzudzu ndi tizilombo tina touluka. Kukonzekera pepala la tepi: Ikani chingamu cha Chiarabu m’chidebe, onjezerani 1/3 ya madzi mu fomula, kuti lisungunuke kwathunthu, kenako dulani pepala la kraft m’zidutswa, pakani guluu pa pepala la a ndi B kraft, liume. Pangani guluu wa ntchentche: ikani rosin mu mphika wa porcelain, onjezerani madzi otsala 2/3, tenthetsani, dikirani kuti rosin isungunuke, kenako tenthetsani madzi kuti atuluke, pamene madzi mumphika auma mofulumira, onjezerani mafuta a paulowne ndi mafuta a castor, sakanizani bwino, kenako onjezerani uchi mofanana, pitirizani kutentha madzi ochulukirapo kuti atuluke.
