Pakutumira simba kwemuchina kunochinjika, basa risingashandiswi zvakanyanya panguva yekutumira simba, zvinoita kuti simba rive nani. Pakutumira simba kwebhandi rakajairika rakatsetseka, huremu hwebhandi, nzvimbo yakaputirwa nedhayamita yevhiri uye simba rekuwedzera rakagadzika zvinosarudza kushandiswa kwesimba kwebhandi pakuita basa. Nokudaro, kusarudzwa uye kurongeka kwebhandi rekutumira mumidziyo chinhu chakakosha pakuchengetedza simba, uye bhandi rekutumira rine kureba kwakagadzika, muviri webhandi wakapfava uye kukweshana kwenzvimbo zvine mwero ndiyo sarudzo yakanakisa kune vatengi. Bhandi reAnnilte repolyester rinogadzirisa matambudziko ari pamusoro apa zvakanaka.
1. Polyester ine hunhu hwekuchengetedza simba
a) Simba guru rekusimba uye kusimba kwakasimba.
Kazhinji, kana tichienzanisa ne substrate, simba rekutambanudza rakasimba re1% rebhandi repolyester rinokwira ne30% kusvika 50%, zvinoreva kuti bhandi harifanirwe kugadzirisa kushushikana kakawanda mushure mekugadzirisa simba rekumanikidza. Pamusoro pezvo, kushanda kwaro kwakapfava, kushushikana kuri pakati nepakati uye hakusi nyore kurasikirwa nekumhanya, zvekuti mutoro wekutakura unoderedzwa zvishoma, zvichichengetedza kushandiswa kwemagetsi.
b) Matambi acho akareruka pakurema
Rutivi rwakasimba rwebhandi repolyester ichimiro chakakosha chejira repolyester rakasimba-rakaderera-refu, kana simba rimwe chete richitumirwa, unogona kusarudza bhandi rakatetepa rakatsetseka, kuitira kuti kuderedza nguva yekusagadzikana uye simba repakati pebhandi rakatsetseka, kuitira kuti simba rayo rideredzwe uye kushandiswa kwemagetsi kucheneswe.
c) Kuchinjika kwakanaka
Nekuti muviri webhandi repolyester wakapfava, muviri webhandi nevhiri rebhandi zvakaputirwa zvakanaka, kushushikana kwekukotama kunodzikira, kushanda zvakanaka kwekutumira kunovandudzwa uye kushandiswa kwesimba kunochengetedzwa zvishoma.
d) Chinobatanidza chinokurumidzira uye chisingakuvadzi nharaunda
Joini rinoshandisa chisungo chemazino chinonyunguduka chemuviri che thermoplastic elastomer, hapana namatidziro inoiswa, uye kushanda kwacho hakuna kuganhurirwa, saka nguva yekuisa inoponeswa uye kusvibiswa kwezvakatipoteredza kunoderedzwa.
2. Simba rekuchengetedza simba
Kuenzanisa kwemunda kunoratidza kuti avhareji yesimba rekuchengetedza simba repolyester strip yakakwira kupfuura 10% kupfuura iyo yebhendi rechip remuno nerekunze kwenyika.
Kuchengetedza simba kwebhandi repolyester kwakakosha zvikuru, pamuchina wekupenda shinda, simba rekuchengetedza simba rinogona kusvika 20%, pamuchina wepfupi wekumonera shinda mbiri, simba rekuchengetedza simba rinodarika 15%, pamuchina wekumonera shinda ka310, simba rekuchengetedza simba i10%. Saka, bhandi repolyester rine mashandiro aro akanaka ekuchengetedza simba, rave richishandiswa zvakanyanya sebhandi redhiragoni uye bhandi resimba rezvishandiso zvitsva zvinomhanya zvakanyanya zvakaita semuchina wekuvhara shinda, muchina wekumonera wakareba kwazvo, muchina wekumonera werotary uye muchina wekumonera shinda mbiri.
3. Kuenzanisa mashandiro ekuvaka
Bhandi repolyester rakagadzirwa nerabha re carboxyl nitrile butadiene rakagadzirwa sechinhu chikuru che driving ne friction layer, uye mashandiro akafanana nee substrate.
Pepa re thermoplastic polymer elastomer rinoshandiswa sechikamu chekuchinja chakabatanidzwa. Mushure mekuomeswa, zvidimbu zve thermoplastic polymer zvinonyungudutswa uye zvinoburitswa ne extruder kuti zvigadzire pepa rine ukobvu hwakafanana uye upamhi hwe 1200mm. Uye zvichienderana nekukosha kwakasiyana kwebhandi body molding, ukobvu hwakasiyana hwe 0.3 ~ 1.2mm. Chinhu chacho chine hunhu hwekupfava kwakanyanya, kuramba mafuta, kuramba tembiricha, kuramba kuneta, kuchinjika, simba diki rekukweva uye huremu hwakareruka, uye chine hunhu hwakanaka hwekubatanidza ne layer yakasimba nerabha.
