Zomwe zimapangidwira komanso kugwiritsa ntchito akasupe achilengedwe

Thupi katundu:

(A) Kukhazikika

kuchuluka kwa latex yokhala ndi zinthu zolimba komanso mphira wowuma. Zouma mphira zimatanthawuza za mphira wowuma mu latex, zolimba zonse zimatanthawuza kuchotsa madzi ndi zinthu zosasunthika mu latex pambuyo pa zonse zomwe zili muzinthu zolimba, zomwe zimawonetsedwa peresenti. Zonse zolimba ndi zouma mphira nthawi zambiri zimakhala zosiyana, mtengowu umatchedwa kuti wouma, kusonyeza kusasunthika kwa chigawo cha rabala mu latex. Zizindikiro izi zowongolera kapangidwe ndi mtundu wazinthu zili ndi tanthauzo lofunikira.

Kukhazikika kwa latex kwatsopano kumasiyanasiyana ndi mtundu wa zaka zamitengo, nyengo, kusiyana kwa machitidwe, pafupifupi 20% 40% ya zonse zolimba.

(2) Kachulukidwe wachibale

kachulukidwe wachibale wa latex watsopano pafupifupi 0. 96 - 0. 98, amapangidwa ndi kachulukidwe ka whey (1. 02) Ndi kachulukidwe wachibale wa rabara hydrocarbon (0. 9064). Lingaliro, kuchokera pa kachulukidwe wachibale ukhoza kuyerekeza muyeso wa rabara wa hydrocarbon zomwe zili mu latex. Zomwe zili ndipamwamba, kachulukidwe ka latex hidrokaboni wachibale ndi wocheperako, monga momwe tawonetsera patebulo.

(3) Viscosity

okwana olimba zili pafupifupi 35% mwatsopano latex mamasukidwe akayendedwe za 12 - 15 mpa· S, ndi nthawi yosonkhanitsa, ndi zinthu zina ndipo ali ndi kusintha kwakukulu. General okwana olimba zili mkulu mamasukidwe akayendedwe ndi mkulu, koma yemweyo okwana olimba zili lalabala, monga njira kuteteza, yosungirako nthawi, tinthu kukula, ndi zina zotero, kukhuthala kukhuthala wachibale kusiyana zidzachitika.

(4) Kuvuta kwapamtunda

Kuthamanga kwapamwamba kumasonyeza kuti kukula kwa latex kunagawidwa mofanana pamtunda wolimba - ntchito - - - - - - - Kuyima kapena kugwa kwa zomwe zimatchedwa kunyowetsa ntchito. Mphira ndi insoluble m'madzi, koma muli zambiri lalabala akhoza kuchepetsa mavuto padziko madzi pamwamba yogwira zinthu, monga mapuloteni, mafuta zidulo, angathe kuchepetsa mavuto padziko lalabala. Monga okwana okhutira okhutira ndi 38% ~ 40% ya latex, mavuto padziko pafupifupi 38 ~ 40 mn/m, kuposa madzi (72mN/m) Low, ndipo motero pamwamba hydrophilic monga nsalu, zikopa ndi zina nyongolotsi ndi malowedwe luso akhoza zambiri zawonjezeka, monga kuchepetsa kufunika pamwamba pa kukhutitsidwa satisfying technologies, pofuna kuchepetsa kukwanilitsa zofunikira pa nthawi ya teknoloji. ena surfactants, kupititsa patsogolo ntchito pamwamba, kuwonjezera wettability.

（ 5) PH

latex PH imakhudza kwambiri kukhazikika kwake. Latex yatsopano silowerera ndale komanso yamchere pang'ono, PH mtengo wa 7 mpaka 7. 2. Pambuyo maola oposa khumi, chifukwa cha mphamvu ya mabakiteriya ndi michere mu latex akhoza kuchepetsa ndi kukhala acidic PH mtengo, kuti chifukwa cha solidification. Chifukwa chake, nthawi zambiri kuwonjezera ammonia kapena alkali ena, pangani PH mpaka 10 ~ 10. 5, kuti mupulumutse nthawi yayitali.

ntchito:

amagwiritsidwa ntchito makamaka pa: (zopangidwa ndi latex impregnated Tchuthi, zoseweretsa) Baluni, Medical, nyumba, mafakitale) Magolovesi, pacifiers, kondomu;

mankhwala siponji: siponji (Mattresses, pilo, nsapato zakuthupi khushoni pansi);

zopangira jekeseni: zoseweretsa za latex, masks a gasi, zimbudzi, nsapato;

akamaumba mankhwala: mphira masika waya, mankhwala;

: (ntchito zina Tsitsi, zofiirira, nyama ndi zomera ndi kupanga ulusi, chikopa chochita) Gluu, kukhamukira, nonwoven nsalu, kapeti, nsalu, papermaking, ndi zomatira, etc.
