1、Nunɔso a Ɛnnyɛ Foaming ntokuru .

Nea ɛde ba:

(1) ɔhaw ahorow a ɛwɔ aduru a ɛma ahurututu mu yɛ hyew mu;

(2) plasticity a ɛba fam a ɛwɔ rɔba ade no mu;

(3) ɔhyew a ɛkorɔn dodo a wɔde frafra mu ne ade a ɛma ahurututu no popa ntɛm;

(4) wɔde rɔba no si hɔ kyɛ dodo anaasɛ ɛyɛ hyew dodo, na aduru a ɛma ahurututu no yɛ hyew anaasɛ ɛporɔw no bi;

(5) Vulcanization ahoɔhare a rɔba no de tu mmirika no yɛ ntɛmntɛm dodo;

(6) nhyɛso no yɛ kɛse dodo, na ɛboro nhyɛso a ɛwɔ mu a mframa a ɛwɔ aduru a ɛma ahurututu mu no de ba no so, na ɛde ntokuru a ɛwɔ ahurututu mu a ɛdɔɔso ba;

Nneɛma a wɔde ko tia:

(1) hwɛ sɛ ebia aduru a wɔde yɛ ahurututu no wɔ bere tiaa bi mu ne sɛ ebia ɛfata anaa;

(2) Hwɛ sɛ ebia plasticity a ɛwɔ rɔba ade no mu no du gyinapɛn no ho, ɛsɛ sɛ wɔde afrafra dodo no ka ho dodo denam afrafra so, ma plasticity nkɔ soro na ama ntokuru no nkɔso ayɛ mmerɛw;

(3) Hwɛ sɛ ebia ɔhyew a ɛwɔ afiri a wɔde fra nneɛma mu no mu no yɛ kɛse dodo, sɛ ebia ɔhyew a ɛwɔ nhoma mmobɔwee no mu no yɛ kɛse dodo, na sɛ rɔba no ahyew anaa. Wobetumi de rɔba nneɛma bi a ɛwɔ ɔhyew a ɛkɔ soro afra mu ne aduru ketewaa bi a wɔde yɛ adwuma anaasɛ wɔde aduru a ɛma ahurututu mu yɛ den aka ho;

(4) Ɛsɛ sɛ wɔsan de rɔba no kɔ refining no mu ma ɛyɛ adwuma foforo bere a wɔde bere tenten a wɔde si kar no asi hɔ akyi;

(5) Formula nsakrae, hwɛ sɛ ebia ɔhyew a ɛho hia a ɛwɔ vulcanizing agent ne decomposition temperature of foaming agent no bɛn wɔn ho wɔn ho anaa, na ɛne wɔn ho wɔn ho yɛ adwuma ma vulcanization ahoɔhare ne foaming speed hyia;

(6) Yɛ nsakrae wɔ afiri no nhyɛso mu.

2. Nkuku a wɔde hyɛ mu ma a ɛnnɔɔso .

Nea ɛde ba:

(1) rɔba dodow a wɔde di dwuma;

(2) Nkuku a wɔde wie anaa nsunsu a wɔde di dwuma bere tenten dodo a wɔmfa ho ntew, rɔba a ɛsen no yɛ nea wotumi gyina ano;

(3) abura no nhyehyɛe no yɛ den na sɛnea rɔba no tumi sen no ne no nhyia, na mpɛn pii no entumi nhyɛ nkuku no atifi ma bere a wɔde tokuru no ama no akyi, na ɛyɛ sintɔ ahorow;

(4) Wɔrentumi nsɛe mframa a ɛwɔ nkuku no mu a awu no mu, ma enti rɔba no renhyɛ abura no mu ma, na ɛde gluu a enni hɔ no ano aba;

Nneɛma a wɔde ko tia:

(1) sɛ wɔbɛkari pɛ mmiako mmiako de ahwɛ ahu sɛ gluu nneɛma no mu duru yɛ kɛse;

(2) ma rɔba no mu nsu a ɛkɔ so no tu mpɔn;

(3) Sesa nkuku, nhyehyɛe a ntease wom a ɛfa mframa a ɛkɔ mu ntokuru, nsunsu nhyehyɛe, ne nea ɛkeka ho ho.

3. ntokuru a ɛnyɛ pɛpɛɛpɛ (a ɛyɛ kɛse anaasɛ ɛyɛ ketewaa dodo) .

Foam hole no sõ dodo, hardness ne density a ɛwɔ product no mu no nyɛ standard, tokuru a wɔato mu no bɛyɛ joint hole, micro hole no bɛyɛ hole ketewa, afã horow bi bubu anaasɛ parts binom ntumi nkɔ soro.

Nea ɛde ba:

(1) foam agglomeration anaasɛ nneɛma nketenkete no yɛ mmerɛw dodo;

(2) afrafra a ɛnyɛ pɛpɛɛpɛ;

(3) nsu a ɛdɔɔso wɔ aduru a wɔde frafra mu, mframa anaa efĩ a wɔde afra rɔba no mu;

(4) Vulcanization a ɛnnɔɔso, kɔ so nya ntokuru wɔ nkuku no akyi;

Nneɛma a wɔde ko tia:

(1) Hwɛ sɛnea foaming agent no, sɛ ɛsɛ sɛ sieved phenomenon no a, ɛsɛ sɛ wɔbubu particles a ɛyɛ mmerɛw, frafra koraa (anaasɛ thin pass) ma ɛyɛ pɛpɛɛpɛ apete;

(2) Ɛsɛ sɛ nsu a ɛyɛ hyew no yɛ kɛse dodo bere a ayow awie no, yi mframa anaa efĩ a ɛwɔ rɔba ade no mu no fi hɔ, sɛnea ɛbɛyɛ a ɛbɛyɛ mmerɛw koraa.

4. Ahurututu a ɛboro so anaasɛ nea ɛwɔ akyi .

(1) Ahurututu mu a ɛyɛ mmerɛw a ɛboro so .

General surface dicoloration, aniwa ketewa, hardness a ɛkorɔn, product edge cracking, a efi adwumayɛ a ɛmfata, anaasɛ ɔhyew a ɛkorɔn dodo, vulcanization bere tenten dodo anaasɛ nnwinnade a entumi nyɛ adwuma, ɛsɛ sɛ ɛhwɛ sɛ ebia valves ne instruments no wɔ ɔhaw ahorow, na afei wɔde adwumayɛ ho mmara no di dwuma katee.

(2) wɔ vulcanization ase .

Sɛ vulcanization no nnɔɔso a, nhyɛso a ɛwɔ abura no mu no yɛ kɛse sen akyi nhyɛso no bere a woafi nkuku no mu akyi, na sɛ rɔba no kɔ so ma ntokuru no kɔ a, hann no bɛma ayɛ den, ahoɔden a enye ne nsakrae kɛse aba; Nneɛma a emu yɛ duru no bɛma ntokuru no apae. Ɛsɛ sɛ ɛhwɛ sɛ ebia ɔhaw bi wɔ adwinnade ne valve no ho, na ɛde adwumayɛ ho mmara no di dwuma pɛpɛɛpɛ.

Hyɛ no nsow: Foam Products Control quality indicators .

(1) ɛda adi sɛ ɛyɛ den, dodow a ɛyɛ ketewaa no, dodow no ara na eye;

(2) mfiri ahoɔden yɛ 0.5-1.6MPa mpɛn pii;

(3) static compression daa deformation;

(4) ɛyɛ den;

(5) nkɛntɛnso a ɛyɛ den;

(6) ɔbrɛ a ɛkɔ so yɛ den;

(7) onyin ho sɔhwɛ (de digrii 70 * nnɔnhwerew 70; digrii 100 * nnɔnhwerew 24);

(8) Ɔhyew a ɛba fam ho sɔhwɛ.
