Gwajin ingancin sake tarwatsa foda na polymer (RDPs) ya ƙunshi hanyoyi da yawa don tabbatar da aikin su da bin ka'idodin masana'antu. Ga wasu hanyoyin gwajin ingancin gama gari don RDPs:

1. Binciken Girman Barbashi:

• Diffraction Laser: Yana auna girman rabon barbashi na RDPs ta amfani da fasahohin watsawa na Laser. Wannan hanya tana ba da bayani game da ma'anar girman barbashi, girman rabon barbashi, da kuma gabaɗayan ilimin halittar ɗan adam.
• Sieve Analysis: Screens RDP barbashi ta jerin gwargwado masu girma dabam domin sanin girman rabo. Wannan hanyar tana da amfani ga ɓangarorin ɓarke ​​​​amma ƙila ba ta dace da ɓangarorin ƙoshin lafiya ba.

2. Ma'aunin Girman Girma:

• Yana ƙayyade yawan yawan RDPs, wanda shine yawan foda a kowace juzu'in raka'a. Yawan yawa na iya rinjayar kaddarorin kwarara, sarrafawa, da halayen ajiya na foda.

3. Binciken Abun Danshi:

• Hanyar Gravimetric: Yana auna abun ciki na danshi na RDPs ta hanyar bushewa samfurin da auna asarar a cikin taro. Wannan hanya tana ba da bayani game da abun ciki na danshi, wanda ke shafar kwanciyar hankali da ajiyar foda.
• Karl Fischer Titration: Yana ƙididdige abun ciki na danshi a cikin RDPs ta amfani da Karl Fischer reagent, wanda ke amsawa da ruwa musamman. Wannan hanya tana ba da daidaito mai girma da daidaito don ƙayyade danshi.

4. Gilashin Canjin Zazzabi (Tg) Bincike:

• Yana ƙayyade zafin canjin gilashin na RDPs ta amfani da calorimetry daban-daban (DSC). Tg yana nuna sauye-sauye daga gilashi zuwa yanayin rubbery kuma yana rinjayar aikin RDPs a cikin aikace-aikace daban-daban.

5. Binciken Haɗin Sinadarai:

• FTIR Spectroscopy: Yana nazarin sinadarai na RDPs ta hanyar auna sha na infrared radiation. Wannan hanya tana gano ƙungiyoyi masu aiki da haɗin gwiwar sinadaran da ke cikin polymer.
• Binciken Elemental: Yana ƙayyade ainihin abubuwan RDPs ta amfani da dabaru irin su X-ray fluorescence (XRF) ko shayarwar sinadarai (AAS). Wannan hanya tana ƙididdige yawan abubuwan da ke cikin foda.

6. Gwajin Kayayyakin Injini:

• Gwajin ƙwanƙwasa: Yana auna ƙarfin ƙarfi, haɓakawa a lokacin hutu, da kuma yanayin fina-finai na RDP ko sutura. Wannan hanyar tana kimanta kayan aikin injina na RDPs, waɗanda ke da mahimmanci don aikinsu a cikin aikace-aikacen m da gini.

7. Gwajin Rheological:

• Ma'aunin Danko: Yana ƙayyade dankowar tarwatsawar RDP ta amfani da na'urorin na'ura na jujjuya ko rheometers. Wannan hanyar tana tantance halayen kwarara da halayen sarrafa RDP a cikin ruwa ko kaushi na halitta.

8. Gwajin Adhesion:

• Gwajin Ƙarfin kwasfa: Yana auna ƙarfin mannewa na tushen mannen RDP ta hanyar amfani da wani ƙarfi a daidai gwargwado ga mahaɗar ƙasa. Wannan hanyar tana kimanta aikin haɗin gwiwa na RDPs akan sassa daban-daban.

9. Binciken Ƙarfin Ƙarfi:

• Thermogravimetric Analysis (TGA): Ƙayyade kwanciyar hankali na thermal RDPs ta auna nauyi asara a matsayin aikin zafin jiki. Wannan hanyar tana kimanta yanayin zafin bazuwar da halayen lalata yanayin zafi na RDPs.

10. Binciken Karan-Kara:

• Binciken Electron Microscope (SEM): Yana nazarin yanayin halittar jiki da tsarin saman sassan RDP a babban girma. Wannan hanya tana ba da cikakken bayani game da sifar barbashi, girman rarrabawa, da kuma yanayin halittar ƙasa.

Wadannan hanyoyin gwaji masu inganci suna taimakawa tabbatar da daidaito, amintacce, da aikin sake tarwatsa foda na polymer (RDPs) a cikin aikace-aikace daban-daban, gami da adhesives, sutura, kayan gini, da samfuran magunguna. Masu sana'a suna amfani da haɗin waɗannan fasahohin don tantance yanayin jiki, sinadarai, inji, da kayan zafi na RDPs da kuma tabbatar da bin ka'idodin masana'antu da ƙayyadaddun bayanai.
