Uburyo bwo guhindura vuba umwenda udafite ubudodo bushongeshejwe

Mu gikorwa cyo gukoraidafite ubudodo bushongeshejwe, bitewe n'ibipimo by'ubushyuhe, umuvuduko w'umwuka, ibumba, umuvuduko n'ibindi bice by'ikigereranyo, bityo hakaba hakenewe uburyo buhoraho bwo gukora no gukemura ibibazo, kugira ngo ibicuruzwa bigere ku musaruro mwiza. Ibi bikurikira ni ubunararibonye bwavuzwe mu buryo nyabwo bwo gukora kugira ngo urebe:

Icya mbere: Uburyo bwo guhindura imashini

1. Koroshya igitambaro mu gihe ubushyuhe n'umuvuduko w'umuyaga biri hejuru;

2. Gabanya buhoro buhoro ubushyuhe bw'umutwe w'icyuma n'ubushyuhe bw'umwuka ushyushye kugeza igihe igitambaro gisa n'aho gikomeye gato;

3. Andika ubushyuhe bw'umutwe w'icyuma n'ubushyuhe bwa screw muri iki gihe;

4. Hindura umuvuduko w'umuyaga, ingano y'isohoka ry'umukungugu n'intera ifatika kugira ngo umwenda woroshye;

5. Hindura umuvuduko wo kuzunguruka kugira ngo ugere ku gukurura kwuzuye;

6, inkingi ihagaze hakurikijwe umuvuduko w'urusobe rw'amazi, muri rusange ongeramo inkingi ebyiri zihagaze, voltage itajegajega muri 40KV-60kV, intera y'umurongo uhagaze hagati ya cm 5-7 n'ubuso bw'igitambaro, ongeramo buhoro buhoro amashanyarazi atajegajega ashobora kuba, ushobora guhitamo kongeramo nziza, ushobora guhitamo kongeramo negative, bishobora kugenwa n'ikizamini.

Icya kabiri: Hindura imiterere y'ibipimo byo gutangira

1. Ubushyuhe bwa screw: shyira 190 ° C, 230 ° C, 230 ° C..., dogere 230, dogere 270 (ibikoresho 1500 bishongeshejwe ntibirenze dogere 270, bishobora kuba dogere 260);

2, ubushyuhe bw'ingufu: dogere 252, dogere 252..., dogere 252 (muri rusange dogere 240 -dogere 255);

3. Imashini ihindura ecran vuba, pompe yo gupima, akayunguruzo k'umutwe: dogere 240;

4. Ubushyuhe bw'inkono ishyushya: dogere 300, ubushyuhe bw'umwuka ushyushye: dogere 240;

5, umuvuduko w'umuyaga: 0.2-0.5mpa (ibikoresho bya PP by'ubushyuhe buri hasi, umuvuduko w'umuyaga ushobora gutoranywamo ibintu bito, ubushyuhe buri hagati, aho gushonga bigera kuri 1300, umuvuduko w'umuyaga ushobora kuba munini gato);

6. Intera yo gukurura urushundura: cm 15-19;

7. Ingano ya tuyere ihuye n'intera iri hagati y'umutwe wa spinneret n'umurongo w'icyuma gikoresha umuyaga, 1-2mm;

8, umuvuduko wo kuzunguruka kw'imashini ni muto cyangwa muto (umuvuduko muto w'umuyaga, ingano y'isohoka ishobora kuba nto, umuvuduko munini w'umuyaga, ingano y'isohoka ishobora kuba nini).

Icya gatatu: kosora uburyo ibintu bidasanzwe bitunganywa

1. Niba igitambaro kidakonje ku bushyuhe bwinshi busabwa, hashobora kubaho ikibazo mu bijyanye no gushyira ubushyuhe mu mwanya wacyo cyangwa kugenzura ubushyuhe, komeza kongera ubushyuhe kugeza igihe igitambaro cyoroshye;

2. Niba umuvuduko w'umwuka uri munsi ya 0.2mpa kandi ubushyuhe bw'umutwe w'inyuma buri hafi ya dogere 210 cyangwa munsi yabyo, hazabaho ikintu cyo kuguruka kw'indabyo. Birashoboka ko aho gushonga kwa PP spray bishongesha ari hato, cyangwa ubushyuhe buterwa n'ingufu, ikimenyetso cy'umuvuduko w'umwuka kitoroshye, cyangwa ingano y'aho umwuka usohoka n'inguni bitoroshye, bityo uruganda rukora ibikoresho cyangwa uruganda rukora ibikoresho fatizo bagomba kuvugana narwo kugira ngo icyo kibazo gikemuke;

3. Ni byiza gukoresha ibikoresho bifite ubushyuhe buke ku bikoresho binini n'ibikoresho bifite ubushyuhe buringaniye ku bikoresho bito;

4. Muri rusange, iyo umwenda utari woroshye iyo wongewe ku bushyuhe bwinshi, cyangwa utangiye kwangirika, hanyuma ubushyuhe bukarushaho kwiyongera, umwenda utangira koroha. Muri rusange, hari ikibazo ku bikoresho ubwabyo, bityo ni byiza kuvugana n'ubikora, cyangwa hari ikibazo gikomeye cy'ubwiza bw'ibikoresho;

5. Kongeramo masterbatches za electret muri rusange bigomba guhuzwa no guhindura ibipimo bya process. Electron masterbatches zitandukanye zifite ibipimo bya process bihuye, bishobora guhindurwa ku buryo bwiza hakurikijwe iyi gahunda yo guhindura vuba, hanyuma bikagereranywa n'imikorere;

6. Uko ingano ya electret masterbatch ari nini, ni ko ingaruka za electrostatic zizaba nziza. Ariko, uko ingaruka ku mwenda zizaba nyinshi, bityo ni ngombwa kugira ngo habeho uburinganire, kandi intego ni ugukora umwenda neza.

Iv. Icyiciro cyo Gukoresha (Imiterere y'Ubushyuhe)

1, ubushyuhe bwa screw: dogere 190, dogere 230, dogere 230..., dogere 230, dogere 260;

2. Ubushyuhe bw'izuba: dogere 240, dogere 240...dogere 240;

3. Imashini ihindura ecran vuba, pompe yo gupima, akayunguruzo k'umutwe: 245 °;

4. Ubushyuhe bw'inkono ishyushya: dogere 300, ubushyuhe bw'umwuka ushyushye: dogere 220.

Fibre yoroshye kuyishyira mu kirere, cyane cyane iyo ubushyuhe buri hejuru, bityo muri rusange, ubushyuhe bw'umutwe w'ibihumyo n'ubushyuhe bw'umwuka ushyushye bigomba kuba biri hasi, ubushyuhe bw'ibihumyo bugomba kuba buri hejuru, icyarimwe, aho biyungurura, ubushyuhe bugomba kuba buri hejuru, kugira ngo bigabanye inshuro zo gufunga umutwe w'ibihumyo.

Icya gatanu: Ibisobanuro by'igabanuka ry'amashanyarazi

Kugira ngo hongerwe imikorere myiza yo kuyungurura umwuka, hakenewe uburyo bwo gutunganya amashanyarazi no kongeramo amashanyarazi ya electret masterbatch kugira ngo hongerwe ubushobozi bwo kuyungurura amashanyarazi no kuyungurura uduce duto tw’umwuka mu cyuma gitwara gazi neza.

1, umwenda ushongeshejwe nyuma yo gutunganywa na, uretse muri masterbatch cyane ushobora gufata electrostatic, ibikoresho bya PP bishongeshejwe bishobora no kuzana electrostatic, kongeramo ingano nto muri masterbatch cyane ku mukandara w'urufunguzo ingaruka z'umusaruro wa electrostatic muri rusange ni hafi 10-20%, kandi electrostatic irahamye, mu gihe cy'ububiko bukwiye, kugabanuka buhoro, kandi ibikoresho bya PP bishongeshejwe bishobora kuzana amashanyarazi menshi ahoraho, bishobora kugira uruhare runini mu kuyungurura ingaruka nziza, ariko kandi bibora vuba;

2. Kugabanuka k'ubushobozi bwo kuyungurura ntabwo ari kimwe no kugabanuka k'amashanyarazi kwa electret mastermind, ariko kugabanuka k'amashanyarazi kwa shotcrete PP ishongeshejwe bishobora gutuma ubushobozi bwo kuyungurura bugabanuka vuba;

3. Igitambaro gikozwe ku bushyuhe bwinshi n'ubushyuhe bw'umwuka ushyushye gisa n'icyoroshye, ariko gukomera kwacyo ntabwo bihagije. Uko igihe kigenda cyongerwa, igitambaro kizacika intege bigatuma ingaruka zo kuyungurura zigabanuka;

Icya gatandatu: uburyo bwo gukemura ikibazo cyo kunoza ingaruka zo kuyungurura

1, niba ushaka gukora ingaruka zo kuyungurura, mbere ya byose, ntabwo byongera mu bihe bikomeye cyane byo gutunganya no gutunganya, ibisabwa n'imyenda yo kuyungurura ikoze mu buryo bwa fiziki, ushingiye kuri ibi, ushobora kwinjira muri masterbatch, ntuyongere mu gutunganya, ugerageza ingaruka zo kuyungurura z'itandukaniro, nziza muri masterbatch cyane ntuyongeremo, ishobora gukorwa binyuze mu nzira yo kuzunguruka y'amashanyarazi adahindagurika, kugira ngo wongere ingaruka zo kuyungurura z'imyenda yo kuyungurura ikoze mu buryo bwa shimi;

2. Muri rusange, ubushobozi bw'ibanze bwo kuyungurura imyenda ishongeshwa bugomba kugera kuri 60%-80%, hanyuma ubushobozi buhamye bwo kuyungurura bushobora kugerwaho binyuze mu kongeramo electret masterbatch na electret treatment.

Ibivuzwe haruguru bivuga ku bijyanye no: uburyo bwo gukosora vuba igitambaro kidafunze gishongeshejwe, nizeye ko tuzagira ubufasha kuri wewe; Turiuruganda rudashonga rukozwe mu buryo bwa meltblownMurakaza neza kugira ngo mugire inama ~
