Ibinyabutabire bigabanya ubushyuhe (monomer)—bikunze gukorana na oligomer zishobora kuvurwa na UV—ni iminyururu migufi kandi ifite imikorere myinshi ihinduka vuba imiyoboro ikomeye kandi irambye munsi y'urumuri rwa ultraviolet (UV) cyangwa electron beam (EB). Kubera ko ari ibinyobwa bifite ubushyuhe bugenzurwa n'ahantu henshi hashobora kuvura ubushyuhe, bigufasha kunoza umuvuduko wo kuvura, gukomera, ubworoherane, gufatana, no kudakoresha imiti mu gihe bigumisha VOC nke.

Imiti igabanya ubukana bw'indwara ni iki?

Ibinyabutabire bihindura imikorere biba hagati ya molekile nto na polimeri ndende. Muri sisitemu ya UV/EB bikora nk'ibigabanya ubukana (bigabanya ubukana mu gihe bigikomeza gukora muri filime) na crosslinkers (byongera ubucucike bw'urusobe rw'amakuru kugira ngo imikorere irusheho kuba myiza). Imiryango isanzwe y'ingenzi irimo di- na tri-acrylates nka HDDA na TMPTA.

Uburyo UV/EB working

Ingufu za Photoinitiators (UV) cyangwa ingufu za EB zitaziguye zikora radicals zifungura imigozi ibiri ya acrylate kuri monomers na oligomers zawe. Imigozi irakura kandi igahuza mu masegonda make, igatanga firime ikomeye ifite imiterere yihariye. Nta gukaraba bikenewe, ingufu nke zinjira, kandi umusaruro mwinshi usohoka.

Igurishwa rikomeye ry'imitungo

Ubwinshi bw'ibintu bito cyangwa ibikomeye: Monomeri zo mu bwoko bwa viscosity nke (urugero: HDDA) zongerera ibintu bikomeye kandi bigakora nta kintu cyongeyeho.

● Umuvuduko wo kuvura ugereranije n'umuvuduko wo kugenzura: Acrylates muri rusange zivura vuba cyane, zigaha ibyuma bitunganya umuvuduko mu buryo buhamye.

● Ubucucike bwa Crosslink vs. Ubukomere: TMPTA ifite imikorere itatu ituma ubukomere/ubudahangarwa bw'imiti budashobora gukomera ariko ishobora kongera ububobere no kugabanuka; imikorere itandukanye (HDDA) ifasha kuringaniza no gutanga ubworoherane.

● Gufata neza no guhindagurika: HDDA ni uburyo bwo gufata neza ibyuma/pulasitiki no guhindagurika cyane; kuvanga neza bifasha mu kunoza umusaruro.

Guhitamo oligomer ikwiye

● HDDA (1,6-hexanediol diacrylate): ikira vuba cyane, ifite ubukana buke, ifatana cyane na plastiki/ibyuma, ihinduka umuhondo muke; ipima umuvuduko n'ubushobozi bwo gutunganya.

● TMPTA (trimethylolpropane triacrylate): ihuriro rikora ku buryo butatu rifasha mu gukomera cyane, kudakora neza, no kwihuta k'umurongo—koresha neza kugira ngo ucunge ububobere.

Porogaramu z'ibanze(n'uburyo bwo kubikoresha)

Gusiga no gucapa irangi Koresha imvange za monomer kugira ngo ugere ku ntego z'ubushyuhe, umusaruro uvamo, no kuramba kw'ikoreshwa rya nyuma.

● Umusaruro w'intego: vuba ikira, irambika neza, ubukana bwinshi/ubudahangarwa bw'imiti, VOC nkeya.

● Amahitamo asanzwe: HDDA yo kwihuta/gufata neza no kuba umuhondo muke; TMPTA yo gusunika ubukana/ubudahangarwa bw'ibinyabutabire.

● Kwibira mu mazi abira: Inkingi zo gusiga no gucapa inki

Ibikoresho byo gufunga no gufata neza

Komeza igihe cyo gukoresha, imbaraga, n'imikorere y'ubushyuhe/imiti.

● Umusaruro w'intego: ishyirwaho ryihuse, imigozi ikomeye ku byuma / PC / ABS, serivisi irambye.

● Amahitamo asanzwe: HDDA yo gukurura no gukoresha vuba hamwe n'uburyo bukomeye bwo gufatana; TMPTA iyo ukeneye imbaraga z'icyatsi kibisi vuba kandi ufite ubukana bwinshi.

● Kwibira mu mazi menshi: Ibyuma bifunga n'ibifunga

Amaresine yo gucapa no gufotora (SLA/DLP) yakozwe mu buryo bwa 3D

Ubushobozi bwo kuringaniza, imbaraga z'icyatsi kibisi, n'uburyo bwa nyuma bwo gukora.

● Umusaruro w'intego: imiterere myiza, kugabanuka kw'ishusho, gukomera kwahinduwe/HDT.

● Amahitamo asanzwe: HDDA kugira ngo igabanye ubukana no kunoza uburyo inyandiko ikoreshwa; TMPTA kugira ngo yongere ubushobozi bwo guhagarara neza (kuvanga kugira ngo igenzure ububobere).

● Kwibira mu buryo bwimbitse: Ikigo cyo gucapa no gufotora amashusho cya 3D

Umutekano no kubahiriza amategeko

Byombi ni ibikoresho byo kuvura uruhu n'ubuhumekero; koresha uturindantoki, indorerwamo z'indorerwamo, n'umwuka uhumeka. Menya neza ko ibirango n'iyandikwa bihuye neza n'isoko ryawe kandi ukomeze kugira QC ikomeye (ubushyuhe, agaciro ka aside, monomer isigaye, ibara, igice cya gel).
