Kusankha zinthu zolembera

Chomata choyenerera chiyenera kutengera mawonekedwe a chinthucho ndi guluu, mawonekedwe ake, kuyenerera kwake kusindikiza, mphamvu yake yomatira ngati njira yowongolera, koma kugwiritsa ntchito komaliza kokha ndikoyenera, chizindikirocho ndi choyenerera.

1. Maonekedwe a chizindikiro

Kodi chizindikiro chomwe mukufuna chikuoneka bwanji?
Palibe mtundu:chowonekera, chowala, chowonekera bwino, chowonekera bwino kwambiri;
Choyera: choyera chowala, choyera chosawoneka bwino, choyera chofiirira;
Mitundu yachitsulo: golide wonyezimira, golide wosawoneka bwino, golide wa silika; siliva wonyezimira, siliva wosawoneka bwino, siliva wa silika;
Laser: hologram, kapangidwe ka laser.

Kodi mukufuna kugwiritsa ntchito chizindikiro ndi mawonekedwe otani?
Chizindikiro cha chubu chofewa: 370° chivundikiro chonse (chomwe chili ndi mafuta onyezimira) 350° mbali yopanda kanthu;
Kutseka: Kutseka kungachitike kokha mutamatira ndikuyika kutentha kwa chipinda choposa 23℃ kwa maola 24 mutakonza.

Kodi kukula kwa chizindikirocho ndi kotani?
Kuuma: kudziwa mwachindunji kuvutika ndi khalidwe la kupaka; mawonekedwe ndi makhalidwe a zinthu zopaka;
Kukhuthala: kumatsimikiza mwachindunji ngati chizindikirocho chingapachikidwe chokha, komanso kumakhudza ngati chizindikirocho chapotoka komanso mtundu wake.

2. Zinthu zolembera pamwamba zoyenera kusindikizidwa
Zipangizo zodzimatira zokha ndiye zonyamulira zithunzi ndi chidziwitso, kotero kuthetsa kusindikiza kwa zinthu ndi ntchito ya ogulitsa zinthuzo. Mavuto abwino a kusindikiza kwa inki ya UV amawonekera makamaka mu inki yonyowa ndi inki yotuluka, zomwe zimayambitsa mavutowa chifukwa cha zinthu izi:

Mlingo wa luso la wogwiritsa ntchito:Mitundu yosiyanasiyana ya zipangizo, makulidwe osiyanasiyana a inki ndi chithunzi chosiyana chosindikizira zimakhala ndi zofunikira zosiyanasiyana pa chipangizo chowumitsira UV. Pa makina osindikizira, mphamvu yochiritsa UV, liwiro losindikiza ndi makulidwe a inki zitha kusinthidwa, monga momwe wogwiritsa ntchito sangathe kuthana ndi ubale pakati pa wina ndi mnzake, zidzakhudza momwe UV imaumira, ndipo zotsatira zowumitsira zimasonyeza mwachindunji momwe inki imatayikira.

Ubwino wa inki:Ogulitsa inki ya UV akuchulukirachulukira pamsika, khalidwe lake silili lofanana, ndipo wopanga yemweyo wa mitundu yosiyanasiyana ya inki, liwiro lake louma komanso kuchuluka kwake kouma sikuli kofanana. Chifukwa cha inki yokha, inki yonyowa nthawi zonse imachitika (makamaka inki yakuda).

Zipangizo:Zipangizo zosindikizira, makamaka zopyapyala, mphamvu yake pamwamba ndiye chifukwa chachikulu chomwe chimakhudza kulimba kwa inki, koma pazinthu zina (monga BOPP, PP, PET) zimadalira mphamvu ya pamwamba ya corona yokha, sizingathe kukwaniritsa zofunikira za kusindikiza inki ya UV.

3. Katundu wa zinthu zomatira
Makhalidwe osiyanasiyana a zinthu zomatira adzakhala ndi zotsatirapo zazikulu pa kumatira komaliza kwa chizindikirocho. Makhalidwe osiyanasiyana ali ndi zofunikira zosiyana pa guluu.

Ngati mphamvu ya pamwamba ili yochepa, monga HDPE, LDPE, PP, ndi zina zotero, guluu wokhala ndi mphamvu yamphamvu yomatira amafunika.

Mwachitsanzo, mabotolo a PET ndi matumba a PVC okhala ndi mphamvu zambiri pamwamba amamatiridwa, chifukwa cha polarity ya zinthu zomatira, ndikofunikira kuti guluu lisamakhale pa zinthu zomatira, kotero guluu wokhala ndi mgwirizano wolimba uyenera kusankhidwa.

Kaya pali pulasitiki kapena chotsukira chambiri pamwamba pa zinthu zopaka, izi zidzakhudza mphamvu yomangirira ya guluu.

Malo owuma a zinthu zopaka phala, monga mabotolo osalala, nsalu yosalukidwa, malo owuma a mabotolo a PP ndi PE, ayenera kukhala ndi guluu wosinthasintha kwambiri.

4. Mawonekedwe a arc a zinthu zomatira
Malo olembera zinthu zomatira azikhala athyathyathya akamatsegulidwa. Ngati malo onse awiri olembera ali ndi ma curve (malo ozungulira olembera) pambuyo poti malo olembera atambasulidwa, cholinga cholembera sichingapachikidwe bwino. Chifukwa chake, thupi la botolo liyenera kupangidwa kuti lipewe kugwiritsa ntchito mawonekedwe osasinthasintha.

Pambuyo pochotsa mawonekedwe a pamwamba pa zilembo zozungulira, radian yayikulu ndi yokulirapo, zofunikira kuti zinthuzo zikhale zofewa zimakhala zapamwamba kwambiri. Kufewa ndi kuuma ndi njira ziwiri zofananira zowonetsera.
