Mayelana Nezinga Lekhwalithi YeNdebe Ye-PP
1. Inhloso
Ukucacisa izinga lekhwalithi, ukwahlulela kwekhwalithi, umthetho wesampula kanye nendlela yokuhlola yenkomishi yepulasitiki ye-PP yokupakisha i-10g yenkosi entsha.
2. Ububanzi besicelo
Ilungele ukuhlolwa kwekhwalithi nokwahlulela inkomishi yepulasitiki ye-PP yokupakishwa kwe-10g ye-pulp yasebukhosini entsha.
3. Inkomba ejwayelekile
Q/QSSLZP.JS.0007 I-Tianjin Quanplastic “Izinga Lokuhlola Ukwenza Inkomishi”.
I-Q/STQF Shantou Qingfeng “izinto zepulasitiki ezilahlwayo”.
I-GB9688-1988 "Izinga lezempilo lomkhiqizo wokupakisha i-polypropylene lokubumba".
4. Izibopho
4.1 Umnyango Wekhwalithi: unesibopho sokuhlola nokwahlulela ngokwaleli zinga.
4.2 Ithimba Lokuthengiwa Kwempahla Lomnyango Wezokuthutha: elinesibopho sokuthenga izinto zephakheji ngokwaleli zinga.
4.3 Ithimba Lokugcinwa Kwempahla Lomnyango Wokuhlela: elinesibopho sokwamukela ukupakishwa kwendawo yokugcina impahla ngokwaleli zinga.
4.4 Umnyango Wokukhiqiza: uzoba nesibopho sokuhlonza ikhwalithi engavamile yezinto zokupakisha ngokwaleli zinga.
5. Izincazelo kanye Nemibandela
I-PP: Isifinyezo se-Polypropylene, noma i-PP ngamafuphi.Ipulasitiki ye-polypropylene.Kuyi-resin ye-thermoplastic eyenziwe nge-polymerization ye-propylene, ngakho-ke ibizwa nangokuthi i-polypropylene, ebonakala ngokungenabuthi, okunganambitheki, ukuminyana okuphansi, amandla, ukuqina, ukuqina nokumelana nokushisa kungcono kune-polyethylene ephansi yokucindezela, futhi ingasetshenziswa. cishe ku-100 degrees.Izinyibilikisi ezivamile ze-asidi ne-alkali zinethonya elincane kuwo futhi zingasetshenziswa ezitsheni zokudla.
6. Izinga Lekhwalithi
6.1 Izinkomba zemizwa nokubukeka

7. Imithetho yamasampula kanye nezindlela zokuhlola
7.1 Ukusampula kuzokwenziwa ngokuya nge-GB/T2828.1-2003, kusetshenziswa uhlelo olujwayelekile lokusampula lwesikhathi esisodwa, olunezinga lokuhlola elikhethekile i-S-4 ne-AQL 4.0, njengoba kucacisiwe ku-Appendix I.
7.2 Ngesikhathi sesampula, yendlalela isampula endaweni engenalo ilanga eliqondile futhi uyilinganise ngokuyibona ebangeni elivamile elibonakalayo;Noma isampula elibheke efasiteleni ukubona ukuthi ukuthungwa akufani yini, ayikho imbobo yokuphina.
7.3 Ekugcineni isampula yezinto ezi-5 ukuze zihlolwe okukhethekile ngaphandle kokubukeka.
* Isisindo esingu-7.3.1: amasampula angu-5 akhethiwe, akalwa bhalansi ye-elekthronikhi enamandla okuzwa angu-0.01g ngokulandelanayo, futhi alinganiswa.
* 7.3.2 I-Caliber nobude: Khetha amasampula angu-3 bese ukala inani elimaphakathi nge-vernier caliper ngokunemba okungu-0.02.
* 7.3.3 Umthamo: Khipha amasampula angu-3 bese uthela amanzi ahambisanayo ezinkomishini zesampula ezinamasilinda okulinganisa.
* 7.3.4 Ukuchezuka kokuqina komumo wenkomishi ngokujula okufanayo: Kala umehluko phakathi kwezindonga zenkomishi eziwugqinsi kakhulu nezincane kakhulu ekujuleni okufanayo komumo wenkomishi kanye nesilinganiso senani eliyisilinganiso ekujuleni okufanayo komumo wenkomishi.
* 7.3.5 Ubukhulu obuncane bodonga: Khetha ingxenye yomzimba ezacile nangaphansi kwenkomishi, kala ukujiya obuncane, bese ubhala inani elincane.
* 7.3.6 Ukuhlola ukumelana nezinga lokushisa: Beka isampula eyodwa kupuleti loqweqwe lwawo olufakwe ngephepha lokuhlunga, gcwalisa umzimba wesiqukathi ngamanzi ashisayo angu-90℃±5℃, bese uwuhambisa ebhokisini le-thermostatic elingu-60℃ imizuzu engu-30.Qaphela ukuthi ingabe isampula yesitsha sesiqukathi sikhubazekile, nokuthi ingabe ingaphansi lomzimba wesiqukathi liyabonisa noma yiziphi izimpawu zokungenwa kahle, ukuguquguquka kombala nokuvuza.
* 7.3.7 Ukuhlolwa kokuwa: Emazingeni okushisa asekamelweni, phakamisa isampula liye kubude obungu-0.8m, wenze uhlangothi olungezansi lwesampula lubheke phansi futhi luhambisane nomhlabathi oshelelayo usimende, bese ulidedela ngokukhululekile ukusuka ekuphakameni kanye ukuze ubone ukuthi isampula liphelele.Ngesikhathi sokuhlolwa, amasampula amathathu athathwa ukuze ahlolwe.
* 7.3.8 Isilingo sokuxhumanisa: Khipha amasampula angu-5, uwafake ku-Tory yangaphakathi ehambisanayo, bese uvala isivivinyo.
* 7.3.9 Ukuhlolwa komshini: Ngemva kokuvala umshini, bamba ingxenye engezansi engu-1/3 yenkomishi ngomunwe wokukhomba, umunwe ophakathi nendawo nesithupha, cindezela kancane kuze kube yilapho ifilimu yenkomishi yefilimu yekhava iqiniswa ibe yi-arc eyindilinga, bese ubona ukuhlukaniswa kwefilimu nendebe.
8. Umphumela Wokwahlulela
Ukuhlolwa kuzokwenziwa ngokuhambisana nezinto zokuhlola ezishiwo ku-6.1.Uma noma iyiphi into yehluleka ukuhlangabezana nezidingo ezijwayelekile, izobhekwa njengengafanelekile.
9. Izidingo Zokugcina
Kufanele igcinwe endlini engenisa umoya, epholile, eyomile, akufanele ihlanganiswe nezinto ezinobuthi namakhemikhali, futhi ivimbele ukucindezela okukhulu, kude nemithombo yokushisa.
10. Izidingo Zokuthutha
Ezokuthutha kufanele kulayishwe kancane futhi kuthululwe, ukuvimbela ukucindezela okukhulu, ilanga nemvula, akufanele kuhlanganiswe nezimpahla ezinobuthi namakhemikhali.
