Igeragezwa kumitungo ya 3D gucapa Milliar hamwe na HydroxyPropyl methylcellse

1.1ibikoresho fatizo

Sima yegukanye p ⅱ 52.5 sima yakozwe nigihingwa cya sima ya Nanjing 0.05%, 0.10%, 0.20%, 0.30%, kimwe; Igiteranyo cyiza ni umucanga ufite ubunini bwa 0.212 ~ 0.425 mm.

1.2Uburyo bwo kugerageza

1.2.1Imyiteguro y'ibintu

Gukoresha minisiteri miri ya moderi JJ-5, urwango uvanga HPMC, sima n'umucanga uriho, hanyuma wongereho amazi kandi uvange umuvuduko mwinshi), kandi ikizamini cyimikorere gikorwa ako kanya nyuma yo kuvanga.

1.2.2Isuzuma ryimikorere

Icapwa ya minisiteri irangwa cyane cyane no gukomera no gukurikizwa.

Gukomera neza nibyo shingiro ryo kumenya 3D gucapa, kandi minisiteri irasabwa koroshya kandi ntiyikoze umuyoboro mugihe cyo gutunganya. Ibisabwa. Kuvuga GB / T 2419-2005 "kugena amazi ya sima,, amazi ya minisiteri yasigaye ahagaze 0, 20, 40, na 60, na 60 yageragejwe no kugerageza kumeza.

Gushora nabi nurufunguzo rwo kumenya ibya 3D. Birasabwa ko urwego rwacapwe rudasenyuka cyangwa guhindura cyane uburemere bwacyo hamwe nigitutu cyo hejuru. Igipimo cyo gutumanaho no kurwanya kwinjira mu buremere bwacyo birashobora gukoreshwa mu kugiti cya 3D icapiro rya 3D.

Igipimo cyo gutaka ku buremere bwerekana urugero rw'uburyo bukoreshwa mu buremere bwayo, rishobora gukoreshwa mu gusuzuma imikorere y'ibikoresho bya 3D. Iringaniza rifite imiterere, ntoya ya minisiteri munsi yuburemere bwayo, rikaba rifasha gucapa. Reba, shyira minisiteri muri silindrike hamwe na diameter nuburebure bwa mm 100, Ram na vids inshuro 10, hanyuma uzamure inshuro 10, hanyuma uzenguruke inshuro 10, hanyuma uzamure ubutaka bwo kugumana uburebure bwa minisiteri, hanyuma uzamure inshuro 10, hanyuma ukarinda ubutaka bwo gufungwa, kandi ku ijanisha ryibipimo byuburebure bwambere ni igipimo cyo kugabana. Uburyo bwavuzwe haruguru bwakoreshejwe mu kugerageza igipimo cyo kwagumana kwa minisiteri nyuma yo guhagarara kuri 0, 20, 40, na 60 min.

Ikirangantego cya 3D icapiro rifitanye isano itaziguye nuburyo igenamigambi nuburyo bukomeye bwibikoresho ubwabyo, bityo uburyo bwo kurwanya byinjira mu buryo bworoshye, bityo uburyo bwo kurwanya ibyiciro byakoreshwaga mu buryo budashingiye ku igenamigambi mu gihe cyo gushyiraho, kugira ngo tumenye neza. Reba kuri JGJ 7 - 2009 "Uburyo bw'ikizamini kubikorwa byibanze byimiryango yo kubaka minisiteri" kugirango isuzume umuryango wo kurwanya minisiteri.

Byongeye kandi, igicapo cya gantry cyakoreshejwe mugusiba no gucapa urucacagu rwa cube imwe hamwe nurwego rwibanze rwumurongo, hamwe nubugari bwimitwe yo hejuru, nubugari bwintambwe yo hepfo yageragejwe. Icapiro ryinshi ryikibaya ni mm 8, hamwe numuvuduko wa printer ni 1 500 mm / min.

1.2.3Ububiko bwa roho

Ibipimo byurugero nicyerekezo cyingenzi cyo gusuzuma kugirango uranga kandi imikorere yubusinzi, bushobora gukoreshwa mu guhanura imyitwarire igenda ya 3D gucapa. Ubukwe bugaragara bugaragaza ubutwari bwimbere hagati yibice biri mubucuruzi kandi burashobora gusuzuma imyigaragambyo yo gutesha agaciro. Ubushobozi bwa HPMC bwo kwerekana ingaruka za HPMC kuri ectrodique ya 3D gucapa minisiteri. Reba kuri Ratio yo kuvanga mumeza ya 2 kugirango utegure sima Paste P-H0, P-H0.10, P-H.20, P-H0.20, koresha DVNEXT ya Brookfield vipupter kugirango ugerageze ibintu byimiterere. Ubushyuhe bwibidukikije Ubushyuhe ni (20 ± 2) ° C. Igituba cyera kibanziriza abantu 10 kuri 60.0 S-1 kugirango ugabanye neza, hanyuma uhagarike iminsi mikuru 10, hanyuma igiti cyometse kumyaka yorota kuri 0.1 S-1 kugeza 60.

Moderi ya Bingham yerekanwe muri EQ. .

τ = τ0 + μγ (1).

Aho τ ni stress Stress; τ0 ni guhangayika; μ ni virusi ya plastike; γ ni igipimo cy'iminsi.

Iyo ibikoresho bishingiye kuri sima biri muri leta ihamye, virusi ya plastike μ yerekana urwego rwingorabahizi za sisitemu ya colloidal, kandi guhangayikishwa na sante τ0 bivuga imihangayiko ntarengwa ikenewe kugirango dutemba. Ibikoresho bigenda gusa iyo habaye imitwe yogoshe hejuru ya τ0, birashobora gukoreshwa kugirango hagaragaze ingaruka za HPMC ku gice cya 3D icapiro.

1.2.4Ikizamini cy'umutungo

Kuvuga GB / T 17671-1999 "uburyo bwo gupima imiyoboro ya sima", ingero za mirtar zifite ibirindiro zitandukanye za HPMC zishingiye ku mbonerahamwe yo kuvanga mu mbonerahamwe ya 2, kandi iminsi yabo inaniranye n'imbaraga zoroheje.

Nta busanzwe urwego rwibizamini rwimbaraga zo guhuza imigabane hagati ya 3D icapiro rya minisiteri. Muri ubu bushakashatsi, uburyo bwo gucamo bwakoreshejwe mukizamini. 3D icapiro rya 3D ryakize kuri 28 D, hanyuma ukata ibice 3, witwa A, B, C. , nkuko bigaragara ku gishushanyo cya 2 (a). CMT-4204 Imashini yo gupima isi yose (intera 20 KN, icyiciro cyukuri 1, igipimo cyo gupakira 0.08 mm / min) cyakoreshejwe mugushiramo ibice bitatu nyuma yo kunanirwa kunanirwa guhagarara, nkuko bigaragara ku gishushanyo cya 2 (B).

Imbaraga za Interlamiar PR yo kuringaniza zibarwa ukurikije formula ikurikira:

Pb = 2fπa = 0.637 fa (2)

aho f ari umutwaro watsinzwe wikigereranyo; A ni agace kagabanijwe hejuru yicyitegererezo.

1.2.5MicroMorhology

Ikipe ya microscopique y'ibihe bya 3 d yubatswe hamwe na quaning 200 Scanning Microscope ya Electron (SOM) kuva Fei Company, muri Amerika.
