1,Mabowo osakwanira a thovu

Zoyambitsa:

(1) mavuto khalidwe la thovu wothandizira;

(2) pulasitiki yotsika ya zinthu za rabara;

(3) kutentha kwambiri kusakaniza ndi kuwonongeka koyambirira kwa wothandizira thovu;

(4) Rabara imayimitsidwa kwa nthawi yayitali kwambiri kapena kutentha kwambiri, ndipo zina mwazinthu zotulutsa thovu zimasanduka nthunzi kapena kuwola;

(5) Kuthamanga kwa vulcanization kwa mphira ndikothamanga kwambiri;

(6) kuthamanga kwambiri, kupitirira kuthamanga kwa mkati komwe kumapangidwa ndi mpweya wotulutsa thovu, zomwe zimapangitsa kuti mabowo athovu osakwanira;

Zotsutsa:

(1) fufuzani ngati wothandizira thovu ali mkati mwa nthawi yochepa komanso ngati ali woyenerera;

(2) fufuzani ngati pulasitiki ya mphira ikugwirizana ndi muyezo, pulasitiki ndi yotsika kwambiri iyenera kuwonjezeredwa ndi kusakaniza, kuwonjezera pulasitiki kuti ipititse patsogolo mabowo;

(3) Onani ngati kutentha kwa makina osakaniza ndikokwera kwambiri, ngati kutentha kwa mpukutu ndikokwera kwambiri, komanso ngati mphira wawotchedwa. Zida zina za mphira zomwe zimakhala ndi kutentha kwakukulu kosakanikirana zimatha kusakanikirana ndi mankhwala ochepa kapena kuwonjezera makampani otulutsa thovu;

(4) Labala iyenera kubwezeredwa ku kuyengedwa kuti ikonzedwenso pambuyo pa nthawi yayitali yoimika magalimoto;

(5) chilinganizo kusintha, fufuzani ngati kutentha yovuta ya vulcanizing wothandizila ndi kutentha kutentha kwa thovu wothandizila ali pafupi wina ndi mzake, ndi kugwirizana wina ndi mzake kuti vulcanization liwiro ndi thobvu liwiro machesi;

(6) sinthani kuthamanga kwa makina.

2. Kusakwanira kudzaza nkhungu

Zoyambitsa:

(1) Kuchuluka kwa mphira wogwiritsidwa ntchito;

(2) Kusakwanira kwa nkhungu kumaliza kapena nkhungu yomwe imagwiritsidwa ntchito kwa nthawi yayitali popanda kuyeretsa, kutuluka kwa mphira kumatsutsana;

(3) Mapangidwe a patsekeke ndi ovuta ndipo kutuluka kwa mphira sikufanana, ndipo nthawi zambiri sikungathe kudzaza pamwamba pa nkhungu pambuyo potulutsa dzenje, kupanga zolakwika;

(4) Mpweya womwe uli mu ngodya yakufa ya nkhungu sungathe kutulutsidwa, kotero kuti mphira usadzaze ndi patsekeke, zomwe zimapangitsa kuti pakhale kusowa kwa guluu;

Zotsutsa:

(1) Kuyeza kulemera kwa chinthu chimodzi ndi chimodzi kutsimikizira kulemera kwa zomatira;

(2) kusintha madzi a rabara;

(3) Sinthani nkhungu, kapangidwe koyenera ka mabowo otulutsa mpweya, mawonekedwe a nkhungu, etc.

3. Mabowo otulutsa thovu osafanana (aakulu kapena ang'ono kwambiri)

Bowo la thovu ndi lalikulu kwambiri, kuuma ndi kachulukidwe ka mankhwalawo siwofanana, dzenje lotsekedwa lidzakhala dzenje lolumikizana, kabowo kakang'ono kamakhala kabowo kakang'ono, mbali zina zimagwa kapena mbali zina sizingatumizidwe.

Zoyambitsa:

(1) thovu agglomeration kapena particles ndi coarse;

(2) kusanganikirana kosafanana;

(3) madzi ochuluka a mankhwala ophatikizira, mpweya kapena zonyansa zosakanikirana mu rabala;

(4) Kusakwanira vulcanization, pitirizani kupanga mabowo pambuyo pa nkhungu;

Zotsutsa:

(1) fufuzani ndi thovu wothandizila, ngati chodabwitsa cha agglomeration ayenera sieved, coarse particles ayenera wosweka, mokwanira osakaniza (kapena woonda chiphaso) kuti wogawana omwazika;

(2) ndi wothandizila chinyezi ayenera kukhala okwera kwambiri pambuyo kuyanika, kuchotsa mpweya kapena zosafunika mu zinthu mphira, kuti mokwanira vulcanized.

4. Kusokoneza kwambiri kapena kusokoneza

(1) Kusokoneza kwambiri

General padziko ma discoloration, yaing'ono eyelet, mkulu kuuma, mankhwala m'mphepete akulimbana, chifukwa ntchito molakwika, kapena kutentha kwambiri, yaitali kwambiri vulcanization nthawi kapena kulephera chida, ayenera kufufuza ngati mavavu ndi zida ndi mavuto, ndiyeno mosamalitsa kutsatira malamulo opaleshoni.

(2) pansi pa vulcanization

Pamene vulcanization sichikwanira, kupanikizika kwamkati kwa pore kumakhala kwakukulu kuposa kuthamanga kwakunja pambuyo pochoka pa nkhungu, ndipo ngati mphira ikupitiriza kutumiza mabowo, kuwalako kumayambitsa kuuma kochepa, mphamvu zopanda mphamvu ndi kusinthika kwakukulu; cholemera chidzachititsa kuti mabowo aphulike. Iyenera kuyang'ana ngati pali vuto lililonse ndi chida ndi valavu, ndikutsatira mosamalitsa malamulo ogwirira ntchito.

Zindikirani: Zinthu za thovu zimayendetsa zizindikiro za khalidwe

(1) Kuchulukitsitsa kowoneka, kucheperako kumakhala bwinoko;

(2) mphamvu yamakina nthawi zambiri imakhala 0.5-1.6Mpa;

(3) malo amodzi psinjika okhazikika mapindikidwe;

(4) kuuma;

(5) zimakhudza elasticity;

(6) kutopa kosalekeza kwamphamvu;

(7) mayeso okalamba (madigiri 70 * maola 70; madigiri 100 * maola 24);

(8) otsika kutentha mayeso.
