Guruu Rinopisa Rinonamira Rinonamira Zvipembenene

Tsananguro yeChigadzirwa

Kushandiswa kweViscose shellac

Chekutanga, inoshandiswa kugadzira bhandi rinonamira renhunzi, ndiro yehonye inonamira, nezvimwewo. Shellac inonamira yakasiyana inogona kushandiswa kugadzira tepi inonamira, bhodhi rinonamira, bhodhi rinonamira renhunzi, imba yepete, nezvimwewo. Chinhu chikuru chedambudziko ndechekuti: zvigadzirwa zvakasiyana zvinofanirwa kushandisa viscose shellac yakasiyana, hazvigone kushandiswa nevanhu vose. Maitiro ekugadzira zvigadzirwa izvi mumaindasitiri akura uye akaumba cheni yakazara yemaindasitiri.
Chechipiri, isa hunde zvakananga. Dambudziko rinowanzoitika pakushandisa shellac zvakananga pamatanda emiti nderekuti zvakaoma zvikuru kuisa. Kuti dambudziko iri rigadziriswe, vagadziri vakasiyana vakaedza nzira dzakasiyana-siyana, uye hapana mhinduro yakachipa kwemakore mazhinji. Mhinduro inowanzo shandiswa ndeyekugadzirisa fomura ye viscose shellac kuti iite kuti ive yakanyunguduka. Zvisinei, mashandiro echigadzirwa akaderera zvikuru, uye hachigoni kunzi viscose shellac.” “Injectable shellac” inogadzirisa matambudziko ari pamusoro apa.
Chechitatu, zvichienderana ne phototaxis dzakasiyana dzezvipembenene zvakasiyana, zvakagadzirwa nemavara akasiyana kuti zvikwezve zvipembenene. Shellac yero inonamira inoiswa pabhodhi chena rinotakura zvinhu kuti igadzire bhodhi yero, uye shellac yebhuruu inoiswa pabhodhi chena rinotakura zvinhu kuti igadzire bhodhi yebhuruu, iyo inoshandiswa kuparadza zvipembenene zvakaita se thrips. Shellac ye viscose chena ine mukaka inoiswa pabhodhi chena rinotakura zvinhu, iyo inoshandiswa kugadzira bhodhi chena re armyworm, iyo inoshandiswa kuparadza zvipembenene zvakaita se diamond-moth.

Kurongwa kweViscose shellac

Viscose shellac Zvichienderana nenzvimbo dzakasiyana dzekushandiswa, viscose shellac inogona kukamurwa kuita mhando mbiri dzinotevera:
(1) Goko rinonamira remukati rakakodzera kushandiswa munzvimbo yekugara, senge: guruu rinonamira renhunzi, guruu remapete, nezvimwewo. Rinoonekwa nekunamira kwakaderera pane rudzi rwemunda, tekinoroji iri nyore yekugadzira uye kugadzirwa kunochinjika.
(2) Zvinonamira zvemhando yemunda zvinoshandiswa mumamiriro echisikigo kuparadza zvipembenene, zvakaita se: haha ​​glue, gun glue shellac, injection glue shellac. Hunhu hwazvo ndehwekuti: kunamira kwakasimba, kudzivirira kukwegura, maitiro akaoma ekugadzira, zvinodiwa zvakanyatsonaka.

Zvichienderana nemafomu akasiyana, yakakamurwa kuva mhando dzinotevera:

(1) Zvigadzirwa zverudzi urwu zvinodzivirira zvakatipoteredza zvinopisa zvinonyunguduka zvakaoma kugadzirira uye zvinodhura zvakanyanya.
(2) Zvigadzirwa zvemhando iyi zvinonzwa kumanikidzwa kwerosin zvinowanzo shandiswa pakugadzira viscose shellac yemukati. Mafekitori mazhinji ekugadzira epamba anoshandisa rudzi urwu rwe shellac inonamira. (3) Mamwe marudzi e viscose shellac anonzwa kumanikidzwa haana kuenzana muzvakanaka nezvakaipa, uye zvakaoma kusiyanisa pakati pechokwadi nenhema.

Zvichienderana nechitarisiko che shellac inonamira, inogona kukamurwa kuita:

(1) Guruu risina ruvara kana kuti jena rakaita semukaka, rudzi urwu rweguruu rune mhando yepamusoro. Rine hushamwari kune zvakatipoteredza uye rakakodzera kushandiswa mumunda.
(2) Guruu reyero rakareruka, chikamu chikuru cherudzi urwu rweguruu rinonamira rosin, chikamu chidiki musanganiswa wepolybutene wemhando yepasi, uye vamwe vanoshandisa polypropylene, polybutene yakasanganiswa kuita viscose shellac.
(3) Guruu dema, rudzi urwu rweguruu rinonamira rinonzwa kumanikidzwa kwerudzi rwerabha, rine hwema husina kunaka uye rinonyanya kushandiswa kugadzirisa makonzo.

Nzira yekubvisa:

1. Kana yangonamirwa, inogona kunyikwa mumvura inodziya yozocheneswa nesipo yekugezesa.
2. Kana guruu rakanamira pamaoko, unogona kushandisa mafuta ekubikisa kuchenesa nekupfavisa, kuchenesa guruu, wozosuka mafuta kubva pamaoko nesipo.
3. Unogonawo kukwesha newaini chena, wobva wanyika mumvura inodziya kuti ubvise namatidza. Ruzivo rwakawedzerwa Rudzi rwepepa rinonamira rinoshandiswa kubata nhunzi. Kana richishandiswa, bepa rinonamira rinosimudzwa kubva kumucheto kwepepa nemaoko, roiswa panzvimbo inowanzo bhururuka nhunzi kana kuti yakakora, chero bedzi nhunzi ikabata kana kuwira papepa, rinonamira zvakasimba. Kana rikasungirirwa pedyo nechiedza, rinogonawo kunamira umhutu nezvimwe zvipembenene zvinobhururuka. Kugadzirira bepa retepi: Isa chingamu cheArabic mumudziyo, wedzera 1/3 yemvura mufomura, kuitira kuti inyunguduke zvachose, wobva wacheka bepa rekraft kuita zvidimbu, puruzira guruu pabepa rekraft re a ne B, woomesa. Gadzira guruu renhunzi: isa rosin muhari yeporcelain, wedzera mvura yasara 2/3, pisa, mirira kuti rosin inyunguduke, wobva wapisa mvura, kana mvura iri muhari yaoma nekukurumidza, wedzera mafuta epaulowne nemafuta ecastor, kurunga zvakanaka, wobva wawedzera huchi zvakaenzana, ramba uchipisa mvura yakawandisa.
