Nekufambira mberi kuri kuita maindasitiri netekinoroji yemazuva ano, kushandiswa kwemakemikari mukugadzirwa kwezuva nezuva uye muhupenyu kuri kuramba kuchiwedzera. Mukuita uku, basa rinokosha ihydrolysis stabilizer. Munguva pfupi yapfuura, kukosha kwezvinosimbisa hydrolysisuye kushandiswa kwadzo mumaindasitiri akasiyana-siyana kwakaongororwa zvakadzama.

Zvigadziriso zvehydrolysis, semushonga wemakemikari unogona kudzivirira zvinhu zvemakemikari kuti zvisaora mumvura, zvinokosha pachena. Mumaindasitiri ezvekudya nezvizoro, zvinogadziriso zvehydrolysis zvinogona kuwedzera hupenyu hwezvigadzirwa uye kuona kugadzikana uye kuchengetedzeka kwezvigadzirwa panguva yekushandiswa. Panguva imwe chete, muindasitiri yemishonga, zvinogadziriso zvehydrolysis zvinoitawo basa guru mukudzivirira mishonga kubva kuhydrolysis.

Zvinotaurwa kuti kune mhando dzakawanda dzezvinodzivirira hydrolysis, zvinosanganisira phenolic antioxidants, phosphate antioxidants, alcoholamine antioxidants, nezvimwewo. Mhando dzakasiyana dzezvinodzivirira hydrolysis idzi dzinoita mabasa akasiyana mukushandiswa kwakasiyana zvichienderana nemaumbirwo adzo akasiyana emakemikari uye hunhu hwadzo.

Zvakakosha kutaura kuti zvinosimbisa hydrolysis zvinonyanya kushandiswa muindasitiri yezvizoro. Nekuwedzera huwandu hwakakodzera hwehydrolysis stabilizer, zvizoro zvinogona kuvandudza kugadzikana kwazvo uye kugona kweantioxidant, nokudaro zvichiwedzera hupenyu hwesherufu uye kuvandudza mashandiro ekushandisa. Panguva imwe chete, zvinosimbisa hydrolysis zvinogonawo kusanganiswa nezvimwe zvinodzivirira antioxidants kana zvinochengetedza kuti zviite basa rekubatana muzvizoro, zvichiwedzera kugadzikana uye kugona kwekuuraya utachiona kwechigadzirwa.

Zvinosimbiswa kuti kunyangwezvinosimbisa hydrolysisZvine basa rakakosha mukuvandudza kunaka kwechigadzirwa uye kugadzikana kwacho, zvakakoshawo kudzora huwandu hwekushandiswa kwacho panguva yekushandisa uye kudzivirira kuchishandisa munzvimbo dzisina njodzi dzakadai semuromo nemaziso kuti uve nechokwadi chekuti kushandiswa kwacho kwakachengeteka.

KUSHANDISA

1. Indasitiri yepurasitiki nerabha

Mukugadzirwa kwezvigadzirwa zvepurasitiki nerabha, zvinosimbisa hydrolysis zvinoita basa rakakosha mukudzivirira hydrolysis kuti isakonzere kuputsika kwecheni yemamorekuru uye kudzikira kwekushanda kwayo. Semuenzaniso, muzvigadzirwa zvepurasitiki zvinoshandiswa panze, kuwedzera zvinosimbisa hydrolysis kunogona kuvandudza zvakanyanya kusimba kwavo kwemvura uye kusimba kwehunyoro nekupisa, uye kuwedzera hupenyu hwavo hwekushanda. Pamusoro pezvo, zvinosimbisa hydrolysis zvinoitawo basa rakakosha mukushandiswa kwakadai sekugadzirisa mukati nekunze kwemotokari uye dzimba dzemidziyo yemagetsi.

2. Indasitiri yemishonga yezvipembenene

Zvinhu zvikuru zvinoshandiswa mumishonga yekuuraya zvipembenene zvinowanzo sanganiswa nemvura uye zvinorasikirwa nebasa razvo.Zvinosimbisa hydrolysisanoshandiswa zvakanyanya mumishonga yezvipembenene uye anogona kudzivirira zvinobudirira kuita kwemishonga yezvipembenene ine acid, alkali, tembiricha nezvimwe, zvichiita kuti mishonga yezvipembenene igare kwenguva refu uye ishande zvakanaka. Kushandiswa uku hakungobatsiri chete kushandiswa kwemishonga yezvipembenene, asiwo kunoderedza kukanganisa kunogona kuitwa nemishonga yezvipembenene nharaunda.

3. Stabaxol series yeRhein Chemie

Chinogadzirisa simba reStabaxol chinorwisa hydrolysis chakatangwa neRhein Chemie (LANXESS) chinopa dziviriro yakanaka yehydrolysis yepolyurethane elastomers uye thermoplastic polyurethane materials (TPU). Mishonga yemvura inorwisa hydrolysis yakaita seStabaxol P 200 inogona kuwedzerwa nyore nyore kumapolymer polyols kuti polymer igare yakasimba kwenguva yakareba. Mu automotive shock absorption system, Stabaxol inodzivirira assistant shock absorption spring kuti isaparadzwe nguva isati yakwana nekuda kwekukwegura kwehydrolysis, zvichiwedzera hupenyu hwebasa. Pamusoro pezvo, Stabaxol inoshandiswawo zvakanyanya muthermoplastic elastomers mukugadzirwa kwetambo, zvichideredza kunzwisisika kwe ester-based elastomers kune hydrolysis.

4. Indasitiri yezvekudya nezvizoro

Zvigadzikiso zvehydrolysis zvinoshandiswawo zvakanyanya muindasitiri yechikafu nezvizoro. Muchikafu, zvinogadzikisa hydrolysis zvinogona kuwedzera hupenyu hwechikafu uye kuchengetedza kunaka uye kukosha kwekudya kwechikafu. Muzvizoro,zvinosimbisa hydrolysisinogona kuvandudza kugadzikana uye kugona kwezvizoro kurwisa ma antioxidants, ichivimbisa kuchengetedzeka uye kushanda zvakanaka kwezvigadzirwa panguva yekushandisa.

Muchidimbu,Zvigadzirisi zvehydrolysis zvine basa rakakosha muindasitiri yemazuva ano. Mashandisirwo azvo akasiyana-siyana haangogadzirisi mhando nekugadzikana kwezvigadzirwa chete, asiwo anokurudzira budiriro inoenderera mberi yeindasitiri dzine chekuita nazvo.
