Gulu la zomaliza

Njira zomaliza zitha kugawidwa m'magulu awiri:

(a) Zakuthupi kapena zamakina

(b) Mankhwala.

Zochita zakuthupi kapena zamakina zimaphatikiza njira zosavuta monga kuyanika pa silinda yotenthetsera nthunzi kumitundu yosiyanasiyana ya makalendala, kukweza zofewa pamwamba pa nsalu ndikuphwanya kumaliza kwa zinthu zodzazidwa kuti mumve bwino.

Zomaliza zambiri zamakina zimadziwika kuyambira kale ndipo zosintha zochepa zachitika munjira yawo yogwirira ntchito.Zina mwakuthupi, monga kukhazikika kwa dimensional, zitha kusinthidwa ndi kumaliza kwa mankhwala.

Kumaliza kwamakina kapena 'kumaliza kowuma' kumagwiritsa ntchito mawonekedwe akuthupi (makamaka makina) amatanthauza kusintha mawonekedwe a nsalu ndipo nthawi zambiri amasinthanso mawonekedwe a nsalu.Zotsirizira zamakina zimaphatikizira kuwerengera, kutuluka, kucheperachepera[1]kukalamba, kukweza, kupukuta ndi kumeta ubweya kapena kudula.Zotsirizira zamakina za nsalu zaubweya ndi mphero, kukanikiza ndi kuyika ndi nkhanu ndi decatising.Kutsirizitsa kwamakina kumaphatikizanso njira zowotcha monga kuyika kutentha (mwachitsanzo, kumaliza kwamafuta).Kumaliza kwamakina kumaonedwa kuti ndi ntchito youma ngakhale kuti chinyezi ndi mankhwala nthawi zambiri zimafunika kuti zitheke bwino.

Kumaliza kwa mankhwala kapena 'kunyowa kumaliza' kumaphatikizapo kuwonjezera mankhwala ku nsalu kuti mukwaniritse zomwe mukufuna.Pomaliza mankhwala, madzi amagwiritsidwa ntchito ngati njira yopangira mankhwala.Kutentha kumagwiritsidwa ntchito kuthamangitsa madzi ndikuyambitsa mankhwalawo.Njira zamakina zasintha ndi nthawi modabwitsa, ndipo zomaliza zatsopano zapangidwa mosalekeza.Njira zambiri zamakina zimaphatikizidwa ndi njira zamakina, monga calendering, kuti zitheke.Kawirikawiri, maonekedwe a nsalu sasintha pambuyo pomaliza mankhwala.

Zomaliza zina zimaphatikiza njira zamakina komanso kugwiritsa ntchito mankhwala.Zomaliza zina zamakina zimafunikira kugwiritsa ntchito mankhwala;mwachitsanzo, othandizira mphero amafunikira kuti agwire ntchito yonse kapena ochepetsera ndi kukonza kuti achepetse kutsimikizira kwa nsalu zaubweya.Kumbali ina, kumaliza kwa mankhwala sikutheka popanda thandizo la makina, monga kunyamula nsalu ndi kugwiritsa ntchito mankhwala.Ntchito yomaliza yamakina kapena mankhwala zimatengera momwe zinthu ziliri;ndiko kuti, kaya chigawo chachikulu cha njira yopangira nsalu ndi makina kapena mankhwala.Zipangizo zamakina zimagwiritsidwa ntchito m'magulu onsewa;kusiyana kwakukulu pakati pa ziwirizi ndi chomwe chinapangitsa kuti nsalu yofunidwa isinthe, mankhwala kapena makina?

Njira ina yogawanitsa ndikuyika zomaliza ngati zomaliza zosakhalitsa komanso zokhazikika.M'malo mwake, palibe kumaliza komwe kumakhala kokhazikika mpaka zinthuzo zitatha kugwiritsidwa ntchito;chifukwa chake gulu lolondola kwambiri lingakhale lokhalitsa kapena lolimba.

Zina mwa zomaliza kwakanthawi ndi:

(a) Zimango: calender, schreinering, embossing, glazing, kuswa, kutambasula, etc.

(b) Kudzaza: wowuma, dongo la china ndi zina zodzaza mchere

(c) Kugwiritsa ntchito pamwamba: mafuta, zofewa zosiyanasiyana ndi zinthu zina zomaliza.

Zina mwazomaliza zokhalitsa ndi:

(a) Kumakina: kutsika kophatikizika, mphero yaubweya, kukwezera ndi kudula njira, perma[1] nent setting, etc.

(b) Kuyika: zopangira zopangira - mkati ndi kunja, mphira latex, laminating, etc.

(c) Chemical: mercerisation, perchmentising, cross-linking agents, water repellent finish, fire resistant and fireproofing finishes, shrink proofing, etc.

Kuyenera kudziŵika kuti gulu lililonse loterolo limakhala losakhazikika.Kugawa molondola kumakhala kovuta chifukwa kulimba kumadalira zinthu zingapo.Kukhalitsa kumatha kukhala kosiyanasiyana, ndipo sikutheka kujambula malire pakati pa zomaliza zosakhalitsa komanso zolimba.

Njira zomaliza zimakhala zosiyana kwambiri moti zimakhala zovuta kuziyika m'magulu.Kwa machira [1] toni, njira zingapo zomalizirira zimagwiritsidwa ntchito kwambiri, koma ndizosiyanasiyana pamachitidwe kotero kuti zimakhala zovuta kuziphatikiza pamodzi.Kwa zaka zambiri, njira zobalalitsira, zomwe ndi mercerisation ndi perchmentization, ndizo zokha zomwe zimatsirizidwa pa thonje, ndipo zikadali zofunika kwambiri lero.Mankhwala omwe amagwiritsidwa ntchito pomaliza izi ndi caustic soda ndi sulfuric acid, motero, mu mawonekedwe okhazikika.
