Iimpawu ezibonakalayo kunye nokusetyenziswa kwemithombo yendalo

Iimpawu ezibonakalayo:

(A) Ukugxininisa

ukuxinwa kwe-latex kunye nomxholo oqinileyo opheleleyo kunye nomxholo werabha owomileyo. Umxholo werabha owomileyo ubhekisa kumxholo werabha owomileyo kwi-latex, umxholo oqinileyo opheleleyo ubhekiselele ekususeni amanzi kunye nezinto eziguquguqukayo kwilatex emva kwawo wonke umxholo wezinto eziqinileyo, ezichazwe ngokwepesenti. Umxholo oqinileyo opheleleyo kunye nomxholo werabha owomileyo kukho umahluko, eli xabiso libizwa ngokuba lilonke elomileyo, ukubonisa ukungaguquguquki komxholo werubha kwi-latex. Ezi zalathisi zokukhokela imveliso kunye nomgangatho wemveliso zinokubaluleka okubalulekileyo.

Ukugxilwa kwelatex entsha kuyahluka ngohlobo lobudala bomthi, ixesha lonyaka, umahluko wenkqubo yokucofa, umyinge wama-20% 40% womxholo oqinileyo uwonke.

(2) Ubuninzi bobudlelwane

Ukuxinana kwelatex entsha malunga ne-0. 96 - 0. 98, yenziwe nge-whey ingxinano yesalamane (1. 02) Kwaye ukuxinana kwerabha hydrocarbon (0. 9064). Isigqibo, ukusuka kuxinaniso olunxulumeneyo sinokuqikelelwa umlinganiselo womxholo werabha we-hydrocarbon kwi-latex. Umxholo uphezulu, ingxinano ye-latex yerabha ye-hydrocarbon incinci, njengoko kubonisiwe kwitheyibhile.

(3) Viscosity

umxholo oqinileyo uwonke malunga ne-35% ye-latex viscosity entsha malunga ne-12 - 15 mpa· S, kunye nexesha lokuqokelela, kunye nezinye izinto kwaye zineenguqu ezinkulu. Isiqulatho esisiqilima ngokubanzi siphezulu i-viscosity ephezulu, kodwa umxholo ofanayo oqinileyo we-latex, njengendlela yokugcinwa, ixesha lokugcinwa, ubungakanani bamasuntswana, njalo njalo, umahluko ohambelana ne-viscosity uya kwenzeka.

(4) Ukuxinezeleka komhlaba

Uxinzelelo lomphezulu lubonisa ukuba ubungakanani belatex basasazwa ngokulinganayo phezu komphezulu oqinileyo - ukusebenza - - - - - - Ukuma okanye ukuwa kokubizwa ngokuba yintsebenzo yokumanzisa. Irabha ayinyibiliki emanzini, kodwa iqulethe i-latex eninzi inokunciphisa ukuxinezeleka komphezulu wezinto ezisebenzayo kumphezulu wamanzi, njengeprotheyini, iiasidi ezinamafutha, zinokunciphisa ukuxinezeleka komphezulu welatex. Njengomxholo oqinileyo opheleleyo yi-38% ~ 40% ye-latex, ukuxinezeleka komphezulu malunga ne-38 ~ 40 mn / m, ngaphezulu kakhulu kunamanzi (72mN / m) Okuphantsi, kwaye ngaloo ndlela umphezulu we-hydrophilic onjengelaphu, ufele kunye nobunye ukumanzisa kunye nokungena amandla kaninzi kunokunyuka, njengokunciphisa iimfuno ze-technology zokunciphisa imveliso ye-technology. ezinye ii-surfactants, ukuphucula ngakumbi ukusebenza komphezulu, ukwandisa ukumanzi.

（ 5) PH

I-latex PH inempembelelo enkulu ekuzinzeni kwayo. I-latex entsha ayithathi hlangothi kwaye i-alkaline encinci, ixabiso le-PH le-7 ukuya kwi-7. 2. Emva kweeyure ukuya kwiiyure ezingaphezu kweshumi, ngenxa yempembelelo yeebhaktheriya kunye ne-enzymes kwi-latex inokunciphisa kwaye ibe yi-acidic PH ixabiso, ukuze unobangela wokuqina. Ke ngoko, rhoqo ukongeza i-ammonia okanye enye ialkali, yenza i-PH ifikelele kwi-10 ~ 10. 5, ukuze ukwazi ukonga ixesha elide.

isicelo:

isetyenziselwa ikakhulu: (iimveliso ezifakwe zelaphu ngeHolide, izinto zokudlala) Ibhaluni, Ezonyango, ezasekhaya, kwimizi-mveliso) Iiglavu, iipacifiers, ikhondom;

iimveliso zesipontshi: isipontshi (oomatrasi, imiqamelo, imathiriyeli yezihlangu kumqamelo ongezantsi)

iimveliso zokubumba inaliti: iithoyi zelatex, iimaski zegesi, izinto zangasese, izihlangu;

iimveliso zokubumba: ucingo lwe-rubber spring, izixhobo zonyango;

: (ezinye izicelo Iinwele, ezimdaka, izilwanyana kunye nezityalo kunye nefayibha yokwenziwa, ulusu olwenziweyo) Iglu, ukuthontelana, ilaphu elingalukwanga, ikhaphethi, ilaphu, ukwenza iphepha kunye nokuncamathelisa, njl.
