Polyaminesinomiririra kirasi yezvakagadzirwa zvehupenyu zvinoratidzwa nekuvapo kweamino mapoka akawanda. Aya makomisheni, ayo anowanzo asina ruvara, gobvu mhinduro padhuze ne kwaakarerekera pH mazinga. Nekuwedzera maamine akasiyana kana ma polyamine panguva yekugadzirwa, zvigadzirwa zve polyamine zvine huremu hwakasiyana hwemamorekuru uye madhigirii emapazi anogona kuwanikwa kuti aenderane kune akasiyana minda yekurapa mvura.
Naizvozvo, mashandisirwo e polyamines anotora maindasitiri akasiyana siyana, anosanganisira kujekeswa kwemvura, kupatsanurwa kwemafuta-mvura, kubviswa kwemavara, kurapwa kwemarara, uye latex coagulation mumiti yerabha. Aya makomisheni anowanawo zvekushandisa muindasitiri yekubikira uye yemapepa, pamwe neakasiyana mashandisirwo akadai sekugadzirisa marara enyama, senge mumarara yehuku. Polyamines anowanikwa mumagiredhi akawanda, ane akasimba kudzika kubva pa50 kusvika 60%.
Mapoliamines anokunda mukubatanidza macolloidal dispersions, kunyanya mudhipoziti yekudzora maapplication ane chekuita nepulp, stock, waya, kana mafewa. Ivo vanonyatsobvisa organics uye ruvara kubva kutenderera kana nzizi dzemvura mu pulp uye mapepa mill. Nekudaro, kusarudza iyo inodhura zvakanyanya polyamine chigadzirwa kunoda kuongororwa kwekuita kwakagadzirirwa kune chaiyo chikafu kana rukova rwakagadzirirwa kurapwa. Polyamines inogona kupihwa zvakachena kana kunyungudutswa mumutsara panguva yekurapwa.
Dosage zvinodiwa zvepolyamines zvinoenderana nekuoma kwenyaya iripo. Kudzora dhipoziti mu pulp kana stock, iyo dosage inowanzobva pa 0.25 kusvika 2.5 kilograms ye polyamine patani ye pulp kana stock (yakaoma base). Paunenge uchigadzirisa nyaya dzedhipoziti pajira rekugadzira, iyo inokurudzirwa dosage inotangira pa0.10 kusvika 1.0 milliliters paminiti paguti yehupamhi hwejira.
Kuchengetedza kwakakodzera uye kubata kwe polyamines kwakakosha kuchengetedza kushanda kwavo. Polyamines inofanira kuchengetwa mukati mekupisa kwe10-32 ° C. Kuratidzwa kwenguva pfupi kune tembiricha kunze kweiyo chiyero kazhinji hakukuvadze chigadzirwa. Kana ichando, polyamines inofanira kudziya kusvika 26-37 ° C uye yakanyatsosanganiswa isati yashandiswa. Hupenyu hwesherufu hwema polyamines hunowanzosvika kumwedzi gumi nemiviri.
Mukushanda kwekushandisa, musanganiswa wePolyamine Flocculants ine PAC (polyaluminium chloride) yakaratidza kukwidziridzwa kwekubvisa turbidity mumaitiro ekurapa mvura. Iyo PAC/polyamine musanganiswa inonyatso dzikisa PAC dosi, inodzikisa yasara aruminiyamu ion concentration mumvura yakabikwa, uye inovandudza turbidity kubviswa.
Panguva yekuchengetedza, polyamines inofanira kuchengetwa mumidziyo yavo yepakutanga, kure nekupisa, zuva rakananga. Kuti uwane yakadzama mirairo yekubata uye kuchengetedza, vashandisi vanofanirwa kutarisa kune chigadzirwa label uye Safety Data Sheet (SDS).
Isu tiri nyanzvimutengesi we polyaminesyekurapa kwemaindasitiri. Polyamine inotengeswa mukambani yedu inogona kushanda zvakanyanya kwenguva yakareba! Bata nesu! ( Email:sales@yuncangchemical.com )
