Cov roj hmab ntuj tuaj yeem muab faib ua cov nplaum nplaum, cov nplaum nplaum, cov nplaum nplaum, thiab cov roj hmab raws li cov txheej txheem tsim thiab cov duab sib txawv.Tobacco nplaum yog lim, solidified rau hauv nyias daim ntawv los ntawm kev ntxiv formic acid, qhuav thiab haus luam yeeb los tsim Ribbed Smoked Sheet (RSS) . Feem ntau ntawm cov roj hmab ntuj tuaj ntawm Tuam Tshoj yog cov nplaum nplaum, uas feem ntau muab faib raws li nws cov tsos thiab muab faib ua tsib theem: RSS1, RSS2, RSS3, RSS4, RSS5, thiab lwm yam. Yog tias nws tsis ncav cuag qib tsib, nws yog cais raws li cov nplaum sab nraud.Standard roj hmab yog latex uas tau raug solidified thiab ua tiav rau hauv cov khoom. Cov roj hmab hauv tsev yog cov qauv roj hmab, tseem hu ua cov roj hmab particle. Domestic standard adhesives (SCR) feem ntau muab faib raws li kev sib koom ua ke ntawm lub cev thiab tshuaj lom neeg thiab cov cim qhia, uas suav nrog xya yam khoom: impurity cov ntsiab lus, tus nqi pib plasticity, plasticity retention rate, nitrogen content, volatile matter content, ash content, and color index. Ntawm lawv, cov ntsiab lus impurity yog siv los ua qhov ntsuas qhov ntsuas, thiab nws tau muab faib ua plaub theem raws li tus nqi ntawm impurities: SCR5, SCR10, SCR20, SCR50, thiab lwm yam, uas yog sib npaug rau thawj, thib ob, thib peb, thiab plaub. qib txheem adhesives nyob rau hauv Tuam Tshoj.Lub ntuj roj hmab muaj nyob rau hauv kev ua lag luam yog tsuas yog ua los ntawm latex los ntawm peb nplooj roj hmab ntoo. 91% mus rau 94% ntawm nws cov khoom yog roj hmab hydrocarbons, hos tus so yog tsis muaj roj hmab yam xws li cov proteins, fatty acids, tshauv, thiab suab thaj. Cov roj hmab ntuj yog cov roj hmab uas siv dav tshaj plaws hauv ntiaj teb.Natural roj hmab yog tsim los ntawm latex, thiab ib feem ntawm cov khoom tsis muaj roj hmab uas muaj nyob rau hauv latex tseem nyob rau hauv cov khoom ntuj roj hmab. Feem ntau, cov roj hmab ntuj muaj 92% rau 95% roj hmab hydrocarbons, thaum tsis muaj roj hmab hydrocarbons suav txog 5% mus rau 8%. Vim muaj ntau txoj kev sib txawv, keeb kwm, thiab txawm tias cov roj hmab sib txawv ntawm cov khoom sib txawv, qhov kev faib ua feem ntawm cov khoom no yuav txawv, tab sis lawv feem ntau nyob rau hauv qhov ntau.Protein tuaj yeem txhawb cov vulcanization ntawm roj hmab thiab ncua kev laus. Ntawm qhov tod tes, cov proteins muaj zog nqus dej, uas tuaj yeem ua kom paub cov roj hmab kom nqus dej noo thiab pwm, txo cov rwb thaiv tsev, thiab tseem muaj qhov tsis zoo ntawm kev tsim hluav taws xob ntau ntxiv.Acetone extracts yog qee cov roj fatty acids thiab sterols, qee yam ua raws li ntuj tsim. antioxidants thiab accelerators, thaum lwm tus neeg tuaj yeem pab tshem tawm cov hmoov additives thaum sib tov thiab muag cov roj hmab nyoos.Ash mas muaj ntsev xws li magnesium phosphate thiab calcium phosphate, nrog me me ntawm cov hlau sib txuas xws li tooj liab, manganese, thiab hlau. Vim tias cov valence hlau ions sib txawv no tuaj yeem txhawb kev laus ntawm cov roj hmab, lawv cov ntsiab lus yuav tsum tau tswj.Cov dej noo hauv cov roj hmab qhuav tsis pub tshaj 1% thiab tuaj yeem evaporate thaum ua. Txawm li cas los xij, yog tias cov ntsiab lus noo noo siab dhau lawm, nws tsis tsuas yog ua rau cov roj hmab nyoos tuaj pwm thaum lub sijhawm khaws cia, tab sis kuj cuam tshuam rau kev ua cov roj hmab, xws li nyiam cov neeg sawv cev sib xyaw ua ke thaum sib tov; Thaum lub sij hawm dov thiab extrusion txheej txheem, npuas yog yooj yim generated, thaum lub sij hawm lub vulcanization txheej txheem, npuas los yog daim txhuam cev zoo li cov qauv tsim.
