Qhov zoo thiab cov khoom ntawm BromoButyl Rubber Stopper

2.1. Piv nrog cov roj hmab butyl zoo tib yam, halogenated butyl roj hmab zoo heev ua rau cov tshuaj tiv thaiv vulcanization. Ntxiv nrog rau muaj cov khoom zoo ib yam li roj hmab butyl, nws kuj muaj vulcanization yooj, tuaj yeem ua vulcanized yam tsis muaj leej faj lossis leej faj pub dawb, tuaj yeem ua vulcanized yam tsis muaj zinc oxide lossis ib qho me me ntawm zinc oxide, muaj qhov ceev vulcanization ceev thiab yuav tsum muaj tus neeg saib xyuas Vulcanizing tsawg dua. thiab lwm yam ntxwv.

 

2.2. Lub hom phiaj yog los txhim kho cov vulcanization kev ua tau zoo ntawm butyl roj hmab thiab txhim kho nws compatibility nrog rau lwm yam roj hmab.

Qhov zoo ntawm bromobutyl roj hmab stopper:

Lub vulcanization txoj hauj lwm nyob rau hauv bromobutyl yog hloov tau ntau tshaj li ntawm chlorinated butyl, yog li cov vulcanization kev ua yog ntau dua thiab cov co-vulcanization muaj peev xwm nrog cov roj hmab ua ke yog zoo dua.

Cov yam ntxwv ntawm bromobutyl roj hmab:

 

3.1 Muaj ntau hom vulcanizing tus neeg sawv cev muaj. Ntxiv rau cov tshuab vulcanizing siv rau chlorinated butyl roj hmab, kuj tseem muaj cov tshuab vulcanizing uas tsis haum rau chlorinated butyl roj hmab, xws li polyamine vulcanization, uas tuaj yeem zam cov sulfur (los yog sulfur-muaj accelerators) thiab oxidation. Lub xub ntiag ntawm zinc ua kom huv dua;

 

3.2 Kev ua haujlwm siab vulcanization, ceev vulcanization ceev, lub sij hawm luv luv, thiab tsawg dua vulcanizing tus neeg saib xyuas ntau npaum li cas;

 

3.3 Qhov ua tau ntawm co-vulcanization nrog cov roj hmab uas tsis muaj roj ntau yog siab;

 

3.4 Cov khoom siv mis muaj qhov cuam tshuam tsawg dua ntawm vulcanization (xws li tsis tshua muaj kev cuam tshuam los ntawm acid, alkali thiab av noo), thiab yog qhov tsim nyog rau kev txhaj tshuaj vulcanization nyob rau hauv cov nqe lus ntawm ntau lawm technology.

Piv nrog cov chlorobutyl roj hmab stoppers, bromobutyl roj hmab stoppers muaj kev ruaj khov, muaj lub neej ntev dua, thiab muaj kev cuam tshuam tsawg dua rau cov tshuaj. Lawv tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau qis-molecular-yuag thrombin inhibitors. Raws li kev sim los ntawm cov tuam txhab txawv teb chaws Kev sib deev pov thawj lees paub qhov no.

 

 

4. Qhov zoo ntawm butyl chloride:

Chlorobutyl roj hmab stoppers muaj kev tiv thaiv tshav kub zoo dua, tsis tshua muaj peev xwm lo thaum siv rau kev ua kom tsis muaj menyuam, thiab muaj txiaj ntsig zoo hauv kev tsim tshuaj hauv Hoobkas.

 

5. Kev sib piv ntawm cov khoom siv feem ntau siv hauv cov tshuaj roj hmab lub raj mis stoppers

 

5.1 Ntuj roj hmab--- siab impurity (protein) cov ntsiab lus, loj zoo sib txawv, thiab nquag latex allergy; tsis haum rau lub raj mis stoppers.

 

5.2 Synthetic isoprene --- muaj huab cua tsis zoo thiab yuav tsum tau sulfur vulcanization; daim ntawv thov ntawm lub raj mis stoppers yog txwv.

 

5.3 Ordinary butyl roj hmab--- yuav tsum tau yooj yim muab cov sulfur thiab accelerator rau vulcanization; tsis pom zoo rau lub raj mis stoppers.

 

5.4 Chlorinated butyl roj hmab--- tuaj yeem ua vulcanized nrog cov tshuaj tsis zoo li qub vulcanizing; thawj lub raj mis tsis muaj sulfur-dawb stopper mis.

 

5.5 Bromobutyl Roj Hmab--- Tso cai siv tus neeg sawv cev tsawg dua vulcanizing; thawj zaug zinc-dawb lub raj mis stopper mis.

 

5.6ExxproTM polymer--- tsis muaj epoxidized soybean roj, antioxidants thiab oligomers;

 

6. Kev sib piv ntawm ob lub roj hmab nres:

 

6.1 Brominated butyl roj hmab stoppers feem ntau vulcanized nrog leej faj thiab muaj me ntsis tsis zoo cua sov. Txij li thaum lub caij bromine yog cov nquag nquag, nws yooj yim los tsim lub qe zoo li tsis hnov ​​tsw (xav tias yuav yog HBr lossis H2S roj) thaum kub kub kom tsis muaj menyuam. Nyob rau tib lub sijhawm, qhov system no yuav tsum tau siv cov vulcanizing tus neeg sawv cev, uas muaj kev cuam tshuam ntau dua rau kev sim hemolysis ntawm cov roj hmab stopper.

 

6.2 Chlorinated butyl roj hmab stoppers feem ntau siv cov tshuab uas tsis yog sulfur vulcanization. Cov khoom muaj cua sov zoo thiab muaj ntxhiab tsw tsawg thaum lub sij hawm kub kom tsis muaj menyuam. Vim tias cov roj hmab tsis muaj epoxidized soybean roj, cov khoom lag luam tsis tuaj yeem ua rau phab ntsa dai lossis opalescence tom qab kev sib cuag nrog tshuaj. thiab lwm yam phenomena.

 

6.3 Qhov sib txawv tseem ceeb ntawm bromobutyl roj hmab thiab chlorinated butyl roj hmab yog tias C-Br daim ntawv cog lus ua haujlwm hauv bromobutyl roj hmab ntau dua li C-Cl daim ntawv cog lus ua haujlwm hauv chlorinated butyl roj hmab, uas txiav txim siab Bromobutyl roj hmab muaj cov yam ntxwv ntawm kev ceev vulcanization ceev, siab. vulcanization efficiency, qib siab ntawm vulcanization, me me ntawm vulcanizing tus neeg sawv cev, thiab muaj peev xwm ua tau sulfur-dawb thiab zinc-dawb vulcanization, yog li muab bromobutyl roj hmab stoppers zoo lub cev thiab tshuaj. , ua rau nws muaj qis hygroscopicity thiab zoo dua siv hauv cov khoom khov-qhuav. Rau qhov tsis tshua muaj qhov hnyav molecular thrombin inhibitor kev daws teeb meem, kev sib koom ua ke ntawm bromobutyl stoppers tau txhim kho zoo; Nyob rau tib lub sijhawm, nws cov ntsuas kev ua tau zoo tshuaj lom neeg tuaj yeem tswj tau hauv ntau qhov zoo, xws li zinc ion<0.00005% (YBB standard <0.0003% ); non-volatile matter (per 100 ml of extract) < 1.0 mg (YYB standard is 4.0 mg); small changes in pH value, etc., thus effectively ensuring compatibility with large infusion products such as amino acids, fat emulsions, and blood products.
