Ibibazo byinshi mugutunganya ibikoresho bivanze

Impamvu nyamukuru zituma habaho "self sulfure" mugihe cyo gushyira ibikoresho bya rubber bivanze ni:

(1) Harakoreshwa ibintu byinshi cyane byangiza kandi byihuta;

(2) Ubushobozi bunini bwo gupakira reberi, ubushyuhe bwinshi bwimashini itunganya reberi, gukonjesha film bidahagije;

.

(4) Parikingi idakwiye, nkubushyuhe bukabije hamwe n’umuvuduko ukabije w’ikirere ahantu haparika.

Nigute wagabanya igipimo cya Mooney cya reberi ivanze?

Mooney ya rubber ivanze ni M (1 + 4), bivuze ko torque isabwa gushyushya dogere 100 kumunota 1 no kuzunguruka rotor muminota 4, nubunini bwimbaraga zibuza kuzenguruka rotor. Imbaraga zose zishobora kugabanya kuzenguruka kwa rotor zirashobora kugabanya Mooney. Ibikoresho fatizo birimo reberi karemano na reberi. Guhitamo reberi karemano hamwe na Mooney nkeya cyangwa kongeramo plasitike ya chimique kumata ya reberi karemano (plasitike yumubiri ntabwo ikora neza) ni amahitamo meza. Rubber ya sintetike mubisanzwe ntabwo yongeramo plasitike, ariko mubisanzwe irashobora kongeramo amavuta make bita dispersants cyangwa ibikoresho byo kurekura imbere. Niba ibisabwa bikomeye bidakomeye, birumvikana ko ingano ya aside stearic cyangwa amavuta nayo ishobora kwiyongera; Niba mubikorwa, umuvuduko wa bolt wo hejuru urashobora kwiyongera cyangwa ubushyuhe bwo gusohora burashobora kwiyongera muburyo bukwiye. Niba ibintu byemewe, ubushyuhe bwamazi akonje nabwo burashobora kugabanuka, kandi Mooney yivanga rya reberi irashobora kugabanuka.

Ibintu bigira ingaruka zo kuvanga imbere yimbere

Ugereranije no kuvanga urusyo, kuvanga imbere bivanga bifite ibyiza byo kuvanga igihe gito, gukora neza, urwego rwo hejuru rwo gukoresha imashini no gukoresha imashini, ibikoresho byiza bya reberi, imbaraga nke zumurimo, gukora neza, gutakaza ibiyobyabwenge bito, hamwe nisuku nziza yibidukikije. Nyamara, gukwirakwiza ubushyuhe mucyumba cyo kuvanga cy’imbere kivanze biragoye, kandi kuvanga ubushyuhe buri hejuru kandi biragoye kubigenzura, ibyo bikaba bigabanya ubushyuhe bwibikoresho bya reberi kandi ntibikwiriye kuvangwa ibikoresho bya reberi yamabara yoroheje nibikoresho bya reberi hamwe nubwoko butandukanye. impinduka. Mubyongeyeho, imvange y'imbere igomba kuba ifite ibikoresho byo gupakurura bijyanye no kuvanga.

(1) Ubushobozi bwo gupakira

Umubare wuzuye wa kole ugomba kwemeza ko ibikoresho bya reberi bishobora guterana cyane no gukata mu cyumba kivanga, kugirango bikwirakwize neza imiti ivanga. Ingano ya kole yashyizweho biterwa nibiranga ibikoresho nibiranga ibikoresho bya kole. Mubisanzwe, kubara bishingiye kubunini bwuzuye bwuruvange rwicyumba hamwe na coefficient yuzuye, hamwe na coefficient yuzuye kuva kuri 0.55 kugeza 0.75. Niba ibikoresho bikoreshwa igihe kirekire, kubera kwambara no kurira mucyumba kivanga, coefficient yuzuye irashobora gushyirwaho agaciro keza, kandi ingano ya kole irashobora kwiyongera. Niba umuvuduko wo hejuru wa bolt uri hejuru cyangwa plastike yibikoresho bifata ni byinshi, ubwinshi bwamavuta nabwo bushobora kwiyongera uko bikwiye.

(2) Umuvuduko wo hejuru

Mu kongera umuvuduko wa bolt yo hejuru, ntabwo ubushobozi bwo gupakira bwa reberi bwiyongera gusa, ariko kandi no guhuza no kwikuramo hagati ya reberi nibikoresho, ndetse no hagati yibice bitandukanye biri mubikoresho bya reberi, birashobora kwihuta kandi kurushaho gukora neza, kwihutisha uburyo bwo kuvanga ibintu bivanga muri reberi, bityo bigabanya igihe cyo kuvanga no kuzamura umusaruro. Muri icyo gihe, irashobora kandi kugabanya kunyerera kw'ibikoresho hejuru yububiko bwibikoresho, kongera imbaraga zo gukata ku bikoresho bya reberi, kunoza ikwirakwizwa ry’imiti ikomatanya, no kuzamura ireme ry’ibikoresho bya reberi. Kubwibyo, kuri ubu, ingamba nko kongera umurambararo wumuyaga wo hejuru wumuyaga cyangwa kongera umuvuduko wumwuka akenshi bifatwa kugirango tunonosore neza hamwe nubwiza bwa reberi ivanze muri mixer y'imbere.

(3) Umuvuduko wa rotor nuburyo bwa rotor

Mugihe cyo kuvanga, umuvuduko wogukoresha ibikoresho bya reberi ugereranije neza na rotor yihuta. Kunoza umuvuduko wogukoresha ibikoresho bya reberi birashobora kugabanya igihe cyo kuvanga kandi nigipimo nyamukuru cyo kunoza imikorere yimvange yimbere. Kugeza ubu, umuvuduko wa mixer y'imbere wongerewe kuva 20r / min wambere kugeza 40r / min, 60r / min, kugeza kuri 80r / min, kugabanya uruvange rwo kuva kuri 12-15 min kugeza kuri l-1.5 min. Mu myaka yashize, kugirango byuzuze ibisabwa byo kuvanga ikoranabuhanga, umuvuduko mwinshi cyangwa umuvuduko wimbere wimbere wakoreshejwe kuvanga. Umuvuduko urashobora guhinduka umwanya uwariwo wose ukurikije ibiranga ibikoresho bya reberi nibisabwa kugirango bigerweho neza. Imiterere yimiterere yimbere ya mixer rotor igira ingaruka zikomeye muburyo bwo kuvanga. Kwiyongera kwa rotor ya elliptique ya mixer y'imbere yiyongereye kuva kuri bibiri kugeza kuri bine, bishobora kugira uruhare runini mukuvanga ubwoya. Irashobora kuzamura umusaruro wa 25-30% no kugabanya gukoresha ingufu. Mu myaka yashize, usibye imiterere ya elliptique, imvange y'imbere ifite imiterere ya rotor nka mpandeshatu na silinderi nayo yakoreshejwe mubikorwa.

(4) Kuvanga ubushyuhe

Mugihe cyo kuvanga ibintu bivanga imbere, hari ubushyuhe bwinshi butangwa, bigatuma bigabanya ubushyuhe. Kubwibyo, ibikoresho bya reberi birashyuha vuba kandi bifite ubushyuhe bwinshi. Mubisanzwe, kuvanga ubushyuhe buri hagati ya 100 na 130 and, kandi ubushyuhe bwo hejuru buvanze kuri 170 kugeza 190 also nabwo bukoreshwa. Ubu buryo bwakoreshejwe mukuvanga reberi yubukorikori. Ubushyuhe bwo gusohora mugihe cyo kuvanga buhoro bugenzurwa kuri 125 kugeza 135 and, kandi mugihe cyo kuvanga vuba, ubushyuhe bwo gusohoka bushobora kugera kuri 160 ℃ cyangwa hejuru. Kuvanga nubushyuhe bwo hejuru cyane bizagabanya ibikorwa byo gukanika imashini ya reberi, bigatuma kuvanga bitaringaniye, kandi bizongera ingufu za okiside yumuriro wa molekile ya rubber, bigabanye imiterere yumubiri nubukanishi bwikigo cya reberi. Muri icyo gihe, bizatera kandi imiti myinshi ihuza imiti hagati ya reberi na karubone yumukara kugirango itange gel nyinshi cyane, bigabanye urugero rwa plastike rwimvange ya reberi, bigatuma ubuso bwa reberi butoroshye, bitera ingorane mugutandukanya no gusohora.

(5) Gukurikirana

Ibikoresho bya plastiki hamwe nuruvange rwababyeyi bigomba kongerwaho mbere kugirango bibe byose, hanyuma ibindi bikoresho bivanga bigomba kongerwaho muburyo bukurikiranye. Iyoroshya rikomeye hamwe nibiyobyabwenge bito byongeweho mbere yo kongeramo ibyuzuye nka karubone yumukara kugirango ubone igihe cyo kuvanga bihagije. Amazi yoroshye agomba kongerwaho nyuma yo kongeramo umukara wa karubone kugirango wirinde agglomeration ningorane zo gutatana; Byihuta byihuta na sulferi byongeweho nyuma yo gukonjesha mumashini yo hepfo, cyangwa muri mixer y'imbere mugihe cyo kuvanga kabiri, ariko ubushyuhe bwabyo bugomba kugenzurwa munsi ya 100 ℃.

(6) Kuvanga igihe

Igihe cyo kuvanga giterwa nibintu bitandukanye nkibikorwa biranga imvange, ingano ya reberi yapakiwe, hamwe na formula yibikoresho bya reberi. Kongera igihe cyo kuvanga birashobora kunoza ikwirakwizwa ryibintu bivanga, ariko igihe kinini cyo kuvanga gishobora kuganisha ku kuvanga byoroshye kandi bikagira ingaruka no kuranga ibirunga bya reberi. Kugeza ubu, igihe cyo kuvanga XM-250/20 ivanga imbere ni iminota 10-12.
