Inzira enye zo guhanagura umugozi wa twin-screw extruder, niyihe ukoresha?

Twin-screw extruders ni imashini zakazi zikora murwego rwo guhuza, kandi imikorere yabo isumba iyindi hamwe nibisanzwe nibyiza byimyanya yabo. Irashobora guhuza inyongeramusaruro zitandukanye hamwe nuzuza kugirango igere kumiterere ya pellet itandukanye hamwe nibikorwa bitandukanye.

Mugihe inyongeramusaruro zitandukanye hamwe nuwuzuza bishobora gutunganywa kugirango bisohore, uburyo bumwe bwo kubona ibyo bicuruzwa burashobora no gukurura ibibazo byanduye hamwe numuvuduko muke cyangwa umuvuduko muke mubice byinshi muri barriel.

Muburyo bukomeza nko gukuramo, kwanduza bishobora kugira ingaruka mbi. Gusukura muri extrait bikunda kuba ingorabahizi kuruta izindi nzira, kandi impanga-twin-screw zihura ningorabahizi zikomeye kuko sisitemu iragoye kuruta gusohora umugozi umwe.

Ubwa mbere, reka turebe uburyo bwo gukora isuku ya twin-screw extruders.

Uburyo bwo gukora isuku ：

Gukoresha polyester resin cyangwa epoxy resin mugusukura bikoreshwa mugusukura ibikoresho bishya cyangwa nyuma ya extruder imaze igihe ikoreshwa, kubera ko ibikoresho bimwe biguma kumurongo cyangwa kuri barriel na gel, umuvuduko wo gukuramo ibintu uratinda, kandi ibara itandukaniro ryamabara ahindura ubwoko ni bunini. Ubu buryo burashobora gukoreshwa. Uyu munsi, hamwe nubukungu bwibicuruzwa byateye imbere cyane, ntihabura isoko ryogusukura ibintu bitandukanye (ibikoresho byogusukura screw) kumasoko, ibyinshi bikaba bihenze kandi bifite ingaruka zitandukanye.

Niba gukoresha isuku yubucuruzi biterwa nababikora bitandukanye nuburyo bwo gukora; amasosiyete atunganya plastike arashobora kandi gukoresha ibisigazwa bitandukanye nkibikoresho byo koza imigozi ukurikije uko umusaruro wabyo ubikora, bishobora kuzigama amafaranga menshi yikigo.

Intambwe yambere mugusukura umugozi ni ukuzimya ibiryo byokurya, ni ukuvuga gufunga icyambu cyo kugaburira hepfo ya hopper; hanyuma gabanya umuvuduko wa screw kuri 15-25r / min hanyuma ukomeze uyu muvuduko kugeza igihe gushonga gutembera kumpera yimbere yurupfu bihagarara gutemba. Ubushyuhe bwa zone zose zishyushya za barrale bugomba gushyirwaho 200 ° C. Barrale imaze kugera kuri ubu bushyuhe, tangira gukora isuku ako kanya.

Ukurikije uburyo bwo gusohora (birashobora kuba ngombwa kuvanaho urupfu kugirango ugabanye ibyago byumuvuduko ukabije kuruhande rwimbere ya extruder), isuku igomba gukorwa numuntu umwe: uyikoresha yitegereza umuvuduko wa screw na torque kumwanya wabyo. , kandi yitegereza igitutu cyo gukuramo kugirango yizere ko sisitemu ya sisitemu itari hejuru cyane. Mugihe cyose, umuvuduko wa screw ugomba kubikwa muri 20r / min. Mugukoresha imitwe yumuvuduko ukabije wumutwe, ntukureho umutwe wapfuye kugirango ubanze usukure. Hagarika kandi ukureho umutwe wapfuye ako kanya mugihe extrudate ihinduwe rwose kuva gutunganya ibisigazwa no kuyisukura, hanyuma hanyuma utangire umugozi (umuvuduko muri 10r / min) kugirango ibisigisigi bisukuye bisohoke.

Ubuyobozi bwo gusenya ：

.

2. Fungura screw extruder ipfa umutwe hanyuma utangire gukora isuku;

3. Hindura umugozi wa twin-screw extruder hanyuma ukureho isahani ya orifice kugirango usohore ibikoresho byo gukaraba bisigaye muri barriel hanyuma usukure isahani ya orifice;

4. Hagarika kandi ukuremo umugozi kugirango urebe niba isukuye, hanyuma ukureho intoki ibikoresho bisigaye kuri screw. Ongera ushyireho umugozi; ongeramo ibikoresho bishya byoza ibikoresho byo gukaraba bisigaye muri barrale hanyuma uhagarike kuzenguruka;

1. Shyiramo isahani ya orifice hanyuma upfe umutwe wa twin-screw extruder kugirango urangize ibikorwa byogukora isuku ya twin-screw.

Uburyo bwo gukora isuku yatetse:

Gukoresha umuriro cyangwa gutwika kugirango ukureho plastike yashyizwe kumurongo ni uburyo busanzwe kandi bunoze bwo gutunganya amashanyarazi. Koresha igihu kugirango usukure ako kanya ako kanya nyuma yo kuyikoresha, kuko muriki gihe umugozi utwara ubushyuhe buva muburambe bwo gutunganya, bityo screw Gukwirakwiza ubushyuhe biracyari bimwe. Ariko ntuzigere ukoresha urumuri rwa acetylene kugirango usukure umugozi. Ubushyuhe bwumuriro wa acetylene burashobora kugera kuri 3000 ° C. Gukoresha urumuri rwa acetylene kugirango usukure umugozi ntabwo bizangiza gusa ibyuma byicyuma, ahubwo bizagira ingaruka zikomeye kubwihanganirane bwimashini.

Niba urumuri rwa acetylene ruhindutse ibara ry'ubururu rihoraho mugihe utetse igice runaka cyumugozi, bivuze ko imiterere yicyuma cyiki gice cyumugozi cyahindutse, ibyo bigatuma kugabanuka kwimyambarire yiki gice, ndetse ndetse kubaho kwa abrasion hagati yo kurwanya anti-matrix. Gukuramo ibyuma. Byongeye kandi, ubushyuhe bwaho hamwe numuriro wa acetylene nabyo bizatera ubushyuhe kuruhande rumwe rwa screw, bigatuma umugozi wunama. Imiyoboro myinshi ikozwe muri 4140.HT ibyuma kandi bifite kwihanganira cyane, muri rusange muri 0.03mm.

Ubugororangingo bwa screw buri muri 0.01mm. Iyo umugati utetse ugakonjeshwa numuriro wa acetylene, mubisanzwe biragoye gusubira muburyo bwambere. Uburyo bukosoye kandi bunoze: Koresha blowtorch kugirango usukure umugozi ukimara gukoreshwa. Kuberako umugozi utwara ubushyuhe muburyo bwo gutunganya iki gihe, gukwirakwiza ubushyuhe bwa screw biracyari bimwe.

Uburyo bwo gukaraba amazi:

Gukaraba neza: Imashini imesa ibyuma byikora byikora ikoresha imbaraga za kinetic yo kuzunguruka kwamazi hamwe ningufu zoguhinduranya za screw kugirango zigere kuri dogere 360 ​​zidafite impande zipfuye. Ifite imikorere ihanitse kandi ntabwo yangiza imiterere yumubiri. Iratahura uburyo bushya bwo gusukura screw muburyo bwangiza ibidukikije, bukora neza kandi buzigama ingufu. Irakwiriye kwamburwa ku gahato no kuvanaho ibikoresho bitandukanye bya polymer, bityo rero ni tekinoroji yo gutunganya icyatsi gifite ingaruka nziza zo gukora isuku.
