Menene kaddarorin jiki da tsarin ginin cellulose don ginawa

Cellulose don gini wani abu ne da aka fi amfani dashi wajen samar da gini. Ana amfani da Cellulose don ginawa a cikin busassun turmi. Bugu da ƙari na ether cellulose yana da ƙasa sosai, amma yana iya inganta aikin rigar turmi kuma yana shafar ginin turmi. Ya kamata a kula da aikin a cikin amfani. Don haka menene ainihin kaddarorin cellulose don gini, kuma menene tsarin ginin cellulose don gini? Idan ba ku da masaniya game da kaddarorin da tsarin ginin cellulose don gini, bari mu kalli tare.

Menene kaddarorin jiki na cellulose don gini:

1. Bayyanar: fari ko kashe-fari foda.

2. Girman barbashi; ƙimar wucewa na raga 100 ya fi 98.5%; Matsakaicin adadin raga na 80 ya fi 100%.

3. Carbonization zafin jiki: 280-300 ° C

4. Girman bayyane: 0.25-0.70 / cm3 (yawanci a kusa da 0.5g / cm3), ƙayyadaddun nauyi 1.26-1.31.

5. Zazzabi mai launi: 190-200 ° C

6. Tashin hankali: 2% maganin ruwa shine 42-56dyn / cm.

7. Soluble a cikin ruwa da wasu kaushi, irin su dace rabo na ethanol / ruwa, propanol / ruwa, trichloroethane, da dai sauransu Aqueous mafita ne surface aiki. High nuna gaskiya, barga yi, daban-daban bayani dalla-dalla na kayayyakin da daban-daban gel yanayin zafi, solubility canje-canje tare da danko, da ƙananan danko, da mafi girma da solubility, daban-daban bayani dalla-dalla na HPMC da wasu bambance-bambance a cikin yi, da kuma rushewar HPMC a cikin ruwa ba ya shafa. ta hanyar pH.

8. Tare da raguwar abun ciki na methoxyl, ma'anar gel yana ƙaruwa, ƙarancin ruwa na HPMC yana raguwa, kuma aikin saman yana raguwa.

9. Har ila yau, HPMC yana da halaye na iyawa mai girma, juriya na gishiri, ƙananan ash foda, kwanciyar hankali na PH, riƙewar ruwa, kwanciyar hankali mai girma, kyakkyawan kayan aikin fim, da kewayon juriya na enzyme, dispersibility da haɗin kai.

Menene tsarin ginin cellulose don ginawa:

1. Abubuwan buƙatun matakin tushe: Idan mannewar bangon matakin tushe ba zai iya biyan buƙatun ba, ya kamata a tsabtace farfajiyar waje na bangon matakin da kyau, kuma yakamata a yi amfani da wakili mai dubawa don ƙara ƙarfin riƙe ruwa na ruwa. bango kuma don haka haɓaka ƙarfin haɗin gwiwa tsakanin bango da allon polystyrene.

2. Layin kula da wasa: tashi sama da layin sarrafawa a kwance da tsaye na ƙofofi na waje da tagogi, haɗin gwiwa, haɗin gwiwa na ado, da sauransu akan bango.

3. Rataya layin tunani: Rataya na'urorin ƙarfe na ƙarfe a tsaye a manyan kusurwoyi (kusurwoyi na waje, sasanninta na ciki) na bangon waje na ginin da sauran wuraren zama dole, kuma rataya layin kwance a wurare masu dacewa akan kowane bene don sarrafa tsayin daka da kwanciyar hankali. polystyrene allon.

4. Shiri na polymer m turmi: Wannan abu ne mai shirya polymer m turmi, wanda ya kamata a yi amfani da bisa ga bukatun na wannan samfurin, ba tare da ƙara wani abu, kamar sumunti, yashi da sauran polymers.

5. Manna grid ɗin da aka jujjuya: Duk wuraren da aka fallasa a gefen allon polystyrene da aka liƙa (kamar haɓakar haɗin gwiwa, haɗin ginin ginin, mahaɗar zafin jiki da sauran sutures a bangarorin biyu, kofofi da tagogi) yakamata a bi da su da grid. .

6. Adhesive polystyrene board: Lura cewa yanke shi ne perpendicular zuwa saman allon. Matsakaicin girman ya kamata ya dace da ka'idodin ƙa'idodin, kuma kada a bar haɗin gwiwa na katako na polystyrene a kusurwoyi huɗu na ƙofar da taga.

7. Gyaran anchors: yawan adadin anchors ya fi 2 a kowace murabba'in mita (ƙara zuwa fiye da 4 don manyan gine-gine).

8. Yi plastering turmi: Shirya plastering turmi bisa ga rabo samar da manufacturer, don cimma daidai gwargwado, inji sakandare stirring, har ma da hadawa.

Daga cikin nau'ikan cellulose da ake amfani da su wajen gine-gine, ether ɗin cellulose da hydroxypropyl methylcellulose ke amfani da shi a cikin busassun turmi shine hydroxypropyl methylcellulose ether. Hydroxypropyl methylcellulose yafi taka rawa wajen riƙe ruwa, kauri da inganta aikin gini a busassun turmi.
