Izakhiwo zomzimba kanye nokusetshenziswa kwemithombo yemvelo

Izici ezingokomzimba:

( A) Ukugxilisa ingqondo

ukugxila kwe-latex enokuqukethwe okuqinile okuphelele nokuqukethwe kwerabha eyomile. Okuqukethwe kwerabha eyomile kubhekisela kokuqukethwe kwerabha eyomile ku-latex, okuqukethwe okuqinile okuphelele kubhekisela ekususeni izingxenye zamanzi nezinto eziguquguqukayo ku-latex ngemva kwakho konke okuqukethwe kwento eqinile, evezwe ngamaphesenti. Isamba sokuqukethwe okuqinile nokuqukethwe kwerabha eyomile ngokuvamile kunomehluko, leli nani libizwa ngokuthi elomile ngokuphelele, ukubonisa ukungaguquguquki kokuqukethwe kwengxenye yerabha ku-latex. Lezi zinkomba zokuqondisa ukukhiqizwa kanye nekhwalithi yomkhiqizo zinokubaluleka okubalulekile.

Ukugxila kwe-latex okusha kuyehluka ngohlobo lweminyaka yesihlahla, isizini, umehluko wesistimu yokuthepha, isilinganiso esingu-20% 40% wengqikithi yokuqukethwe okuqinile.

(2) Ukuminyana okuhlobene

ukuminyana okuhlobene kwe-latex entsha cishe ku-0. 96 - 0. 98, yenziwe nge-whey isihlobo (1. 02) Futhi ukuminyana okuhlobene kwe-rubber hydrocarbon ( 0. 9064). Isinqumo, kusukela ekuminyaneni okuhlobene singalinganisa isilinganiso sokuqukethwe kwerabha ye-hydrocarbon ku-latex. Okuqukethwe kuphakeme, ukuminyana okuhlobene kwerabha yerabha ye-latex kuncane, njengoba kukhonjisiwe kuthebula.

(3) I-Viscosity

ingqikithi yokuqukethwe okuqinile cishe ku-35% we-latex viscosity entsha mayelana ne-12 - 15 mpa· S, nesikhathi sokuqoqa, nezinye izici futhi kunezinguquko ezinkulu. Ingqikithi yokuqukethwe okuqinile okuphelele i-viscosity ephezulu iphezulu, kodwa inani elifanayo lokuqukethwe okuqinile kwe-latex, njengendlela yokulondoloza, isikhathi sokugcina, usayizi wezinhlayiya, nokunye okuhlukile, umehluko ohlobene ne-viscosity uzokwenzeka.

( 4) Ukushuba kobuso

Ukuqina kwe-surface kubonisa ukuthi ubukhulu be-latex basakazwa ngokulinganayo endaweni eqinile - ukusebenza - - - - - - - Isitendi noma ukuwa kwalokho okubizwa ngokuthi ukusebenza kokumanzisa. Injoloba ayincibiliki emanzini, kodwa iqukethe i-latex eningi inganciphisa ukungezwani okungaphezulu kwamanzi asebenzayo, njengamaprotheni, ama-fatty acids, anganciphisa ukungezwani okungaphezulu kwe-latex. Njengokuthi ingqikithi yokuqukethwe okuqinile ingu-38% ~ 40% we-latex, ukungezwani okungaphezulu okungama-38 ~ 40 mn/m, okungaphezulu kakhulu kwamanzi (72mN/m) Okuphansi, futhi ngaleyo ndlela indawo ye-hydrophilic efana nendwangu, isikhumba kanye namanye amandla okumanzisa kanye nokungena ngokuvamile kungakhula, ukuze kuncishiswe izidingo ze-surface satisfying lapho i-tech ingakwazi ukwengeza ukugcwaliswa kwesikhathi. amanye ama-surfactants, ukuze athuthukise ukusebenza kwendawo, andise ukumanzisa.

（ 5) PH

I-latex PH inethonya elikhulu ekuzinzeni kwayo. I-latex entsha ayithathi hlangothi futhi ine-alkaline kancane, inani le-PH elingu-7 ukuya ku-7. 2. Ngemva kwamahora kuya emahoreni angaphezu kweshumi, ngenxa yethonya amagciwane kanye enzyme ku latex kunganciphisa futhi abe acidic PH value, ukuze imbangela ukuqina. Ngakho-ke, ngokuvamile ngokungeza i-ammonia noma enye i-alkali, yenza i-PH ifike ku-10 ~ 10. 5, ukuze ukwazi ukonga isikhathi eside.

isicelo:

isetshenziselwa kakhulu: (imikhiqizo efakwe i-latex efakwe emanzini Iholide, amathoyizi) Ibhaluni, Ezokwelapha, ezasekhaya, zezimboni) Amagilavu, ama-pacifiers, ikhondomu;

imikhiqizo yesipontshi: isipontshi (Omatilasi, imicamelo, impahla yezicathulo emcamelweni ongezansi);

imikhiqizo yokubumba umjovo: amathoyizi e-latex, imaski yegesi, izinto zangasese, izicathulo;

imikhiqizo yokubumba: i-rubber spring wire, izinto zokwelapha;

: (ezinye izinhlelo zokusebenza Izinwele, ezinsundu, izilwane nezitshalo kanye nefayibha yokwenziwa, isikhumba sokwenziwa) Iglu, ukunqwabelana, indwangu engalukiwe, ukhaphethi, izindwangu, ukwenza iphepha, nokunamathelayo, njll.
