Hunhu hwemuviri uye kushandiswa kwezvitubu zvechisikigo

Zvinhu zvenyama:

(A) Kuisa pfungwa

kuwanda kwelatex ine yakazara yakasimba yemukati uye yakaoma rabha yemukati. Dry rubber content inoreva iyo yakaoma rabha yemukati mu latex, yakazara solid content inoreva kubvisa mvura uye zvinonyungudika zvinoumba mulatex mushure mezvese zviri muchinhu chakasimba, chinoratidzwa muchikamu. Yakazara yakasimba yemukati uye yakaoma rabha yemukati kazhinji pane musiyano, kukosha uku kunonzi kuomeswa kwese, kuratidza kusagadzikana kwerubha chikamu chemukati mu latex. Izvi zviratidzo zvekutungamira kugadzirwa uye kunaka kwechigadzirwa zvine kukosha kwakakosha.

fresh latex concentration inosiyana nerudzi rwezera remuti, mwaka, tapping system misiyano, avhareji 20% 40% yehuwandu hwakasimba hwemukati.

(2) Relative density

iyo hama density ye fresh latex inenge 0. 96 - 0. 98, inogadzirwa newhey hama density (1. 02) Uye huwandu hwehukama hwerabha hydrocarbon (0. 9064). Sarudzo, kubva pahuhuremu hunogona kuenzanisa chiyero cherabha hydrocarbon yemukati mulatex. Izvo zvirimo zvakakwirira, latex rabha hydrocarbon hama density idiki, sezvakaratidzwa mutafura.

(3) Viscosity

yakazara yakasimba yemukati inenge 35% yeiyo nyowani latex viscosity ingangoita 12 - 15 mpa· S, nenguva yekuunganidza, uye zvimwe zvinhu uye ine shanduko huru. General yakazara solid solid content high viscosity yakakwira, asi iyo yakafanana yakazara yakasimba yemukati ye latex, senzira yekuchengetedza, nguva yekuchengetera, particle size, zvichingodaro zvakasiyana, viscosity hama musiyano ichaitika.

(4) Kushushikana kwepamusoro

pamusoro tension inoratidza kuti saizi yelatex yakagovaniswa zvakaenzana pamusoro penzvimbo yakasimba - kuita - - - - - - - Kumira kana kudonha kwezvinonzi wetting performance. Rubha haina kunyungudika mumvura, asi ine yakawanda latex inogona kuderedza kushushikana kwepamusoro pemvura pamusoro pemvura inoshanda zvinhu, senge mapuroteni, mafuta acids, anogona kuderedza kushushikana kwepasi kwe latex. Senge iyo yakazara yakasimba yemukati ndeye 38% ~ 40% yelatex, kushushikana kwepasi kwe38 ~ 40 mn/m, kureba kupfuura mvura (72mN/m) Yakaderera, uye nekudaro kweiyo hydrophilic senge jira, dehwe uye kumwe kunyorova uye kupinza kugona kazhinji kunogona kunge kwakawedzera, sekuderedza kugadzirwa kwepamusoro kana kunonoka kugadzirwa kwe tekinoroji. mamwe ma surfactants, kuti awedzere kuvandudza kushanda kwepamusoro, kuwedzera kunyorova.

（ 5) PH

latex PH ine simba guru pakugadzikana kwayo. Fresh latex haina kwayakarerekera uye zvishoma alkaline, PH kukosha kwe7 kusvika 7. 2. Mushure memaawa kusvika maawa anopfuura gumi, nekuda kwesimba rebhakitiriya uye ma enzymes mu latex inogona kuderedza uye inova acidic PH kukosha, kuitira kuti chikonzero chekusimbisa. Naizvozvo, kazhinji uchiwedzera ammonia kana imwe alkali, ita iyo PH kusvika 10 ~ 10. 5, kuitira kuchengetedza kwenguva yakareba.

application:

inonyanya kushandiswa kune: (latex impregnated products Holiday, toys) Bharumu, Medical, mhuri, industry) Magirovhosi, pacifiers, kondomu;

chipanje zvigadzirwa: chipanje (Mattresses, mapiro, shangu zvinhu muzasi cushion);

jekiseni kuumba zvigadzirwa: latex matoyi, gasi masks, zvimbuzi, shangu;

kuumba zvigadzirwa: rubber spring wire, mishonga yezvokurapa;

: (mamwe maapplication Bvudzi, shava, mhuka uye zvidyarwa uye yekugadzira faibha, ganda rekugadzira) Glue, kuyerera, jira risiri rakarukwa, kapeti, machira, kugadzira mapepa, uye anonamira, nezvimwe.
