Kudula mapepala apulasitiki a ABS n'kosavuta ndi zida ndi njira zoyenera, kutengera makulidwe ndi kulondola komwe kumafunika. Umu ndi momwe mungachitire:

Kwa mapepala opyapyala (mpaka 1-2 mm):

Mpeni kapena chida chogoletsa: Goletsani pepalalo motsatira rula ndi ma stripes olimba, mobwerezabwereza mpaka mutadula pakati. Kenako pindani mzere wogoletsa kuti mudule bwino. Sefani m'mbali ndi sandpaper ngati pakufunika kutero.

Lumo kapena zitini: Pa mapepala opyapyala kwambiri kapena odulidwa mopingasa, lumo lolemera kapena zitini zimagwira ntchito bwino, ngakhale kuti m'mbali mungafunike kumalizidwa.

Kwa mapepala apakati (2-6mm):

Jigsaw: Gwiritsani ntchito tsamba lokhala ndi mano ochepa (10-12 TPI) lopangidwira pulasitiki. Mangani pepalalo pamalo okhazikika, lembani mzere wanu ndikudula pa liwiro loyenera kuti musamasungunuke ABS chifukwa cha kukangana. Ziziritsani tsambalo ndi madzi kapena mpweya ngati latentha kwambiri.

Sowo lozungulira: Gwiritsani ntchito tsamba lokhala ndi nsonga ya kabide (mano ambiri, 60-80 TPI). Mangani pepalalo, dulani pang'onopang'ono ndipo lithandizireni kuti lisagwedezeke kapena kusweka.

Pa mapanelo okhuthala (6mm+):

Kudula Patebulo: Monga momwe zimakhalira ndi kudula kozungulira, gwiritsani ntchito tsamba lokhala ndi mano ochepa ndikukankhira bolodilo molunjika. Gwiritsani ntchito choyikapo chopanda kuchotsera kuti muchepetse kusweka.

-Band saw: Yabwino kwambiri podula ma curve kapena makulidwe okhuthala; gwiritsani ntchito tsamba lopapatiza, lokhala ndi mano ochepa ndipo yendani pang'onopang'ono kuti muzitha kulamulira.

Malangizo ambiri:

Kulemba: Gwiritsani ntchito pensulo kapena chizindikiro chokhala ndi rula kapena chitsanzo.

Chitetezo: Valani magalasi oteteza ndi chophimba nkhope - Fumbi la ABS likhoza kukwiyitsa. Gwirani ntchito pamalo opumira mpweya.

Liwiro lolamulira: Kuthamanga kwambiri kumatha kusungunula pulasitiki; pang'onopang'ono kwambiri kumatha kuyambitsa m'mbali zokwawa. Yesani kaye pa zidutswa.

Kumaliza: Konzani m'mbali ndi sandpaper ya grit ya 120-220 kapena gwiritsani ntchito chida chochotsera ming'alu.
Q Ndi pepala liti la pulasitiki lomwe lili bwino, PVC kapena ABS?

A
Kaya PVC kapena ABS ndi 'zabwino' zimadalira zosowa zanu - chinthu chilichonse chili ndi ubwino wosiyana.

PVC ndi yolimba, yotsika mtengo, komanso yolimba kwambiri ku mankhwala, chinyezi, ndi nyengo, zomwe zimapangitsa kuti ikhale yabwino kwambiri kugwiritsidwa ntchito panja (monga mapaipi, zipilala, zizindikiro). Ndi yoletsa moto ndipo siiwonongeka ndi kuwala kwa UV mwachangu monga momwe ABS yosachiritsidwira. Komabe, siigwira ntchito kwambiri, imatha kusweka mukamazizira, ndipo siimakhala yolimba kwambiri.

Mosiyana ndi zimenezi, ABS ndi yolimba komanso yolimba, ngakhale kutentha kochepa, yokhala ndi mawonekedwe owala omwe amawonjezera kukongola (monga zida zamagalimoto, zamagetsi, zitsanzo). N'zosavuta kuumba, makina, ndi guluu; komabe, siilimbana ndi kuwala kwa UV (yomwe imafuna zokhazikika kuti zigwiritsidwe ntchito panja) ndipo imalekerera kutentha pang'ono (imasungunuka pafupifupi 105°C poyerekeza ndi PVC ya 80-100°C, kutengera mtundu wake).
Q Kodi pepala la ABS Plastiki ndi chiyani?

Pepala la ABS (Acrylonitrile Butadiene Styrene) ndi thermoplastic yogwira ntchito kwambiri yomwe imadziwika chifukwa cha kulimba kwake, kuuma kwake, komanso kukana kutentha. Thermoplastic iyi imapezeka m'magawo osiyanasiyana, imapereka zinthu zosiyanasiyana komanso ntchito zosiyanasiyana. Pepala la pulasitiki la ABS likhoza kukonzedwa pogwiritsa ntchito njira zonse zodziwika bwino zokonzera thermoplastic ndipo ndi losavuta kugwiritsa ntchito. Pepala ili limagwiritsidwa ntchito nthawi zambiri pazida zamagetsi, mkati mwa magalimoto, mkati mwa ndege, m'matumba, m'mathireyi, ndi zina zambiri. Mapepala awa amapezeka m'makulidwe osiyanasiyana, mitundu, ndi zomaliza pamwamba, akutsatira miyezo yapadziko lonse lapansi.
